Good AM! Any1 know about a 1000 watts Westrack Brand Assembled Amp... Where to get it, price tag... My friend told me about the amp, his cousin use it for a mobile set up, he dont know the power rating of an Amp.. He says it was bought 2 years ago at Binondo at a Electronic Store, DECIBEZ.. Sad to hear from him he dont know Where it is in Binondo.... Street?? Sketch, LandMarks or Stores beside DECIBEZ for easy hunting.. Any1?? ka pinoyDVD know exact address of DECIBEZ?? Thanks!

Ongpin/F. Torres St.....it is nearby the firestation.....opposite from Watson's.... ;D

WOW!!! Salamat toL.... Merry Christmas!

the stock westrack performance lacks of low sensitivity and impedance drive capability they clip early at my dummy load 6ohms resistor on my osci. Good lang ito for 8ohms full range spectrum of 20 to 20khz use.
Unless you know how to mod and the bias and nfb circuit. its the same circuit as my amp1 and amp2 with steroids.
my designs modded with separate differential regulated supply protecting the pre output driver and final stage out from harm. but the design is not suitable for burst signals that goes beyond 1 to 10hz for some reasons. sometimes it will trick the protection to activate for a few seconds. but if you have subsonic filter it will handle continuous sub freq 15hz to 20khz sweet juice for 24/7.
the real deal is my amp3 and 4 designs. its pure RMS rating is real. it is built for sub frequency abuse use. The feature function is the capability for driving impedance upto to dangerous low 2ohms w/o overheating.
pasyal ka sa house for demo.

i have not bought any kits from them as i diy my own like pilyo here ;D
.....for the cliamed power rating i find the heatsinks too skimpy, you will have to train fans on them to keep them cool when using them on sustained high volume levels.
likewise, all depends on the power tranformer you are going to use as the traffo will determine how much power is delivered to your speakers prior to clipping...
OTOH, having large power traffo may not be wise either as the amp modules can break down when using huge traffos...
so my advice is to use if with extreme care..... ;D

master tony simple ka pa diyan. nakausap ko si william wong owner ng swed westrack. The amp secret really relies on transfo. i now use some techniques to beat costly toroid w/ better efficiency. am doing mas produce on them now. but will accept order ulit on jan 2009 na.
btw train sink like this? choo choo ;D

Kasi yung westRack they are using Transistors like you...2SC2922 and 2SA1216... halus they are they identical sa ginawa mung amp1... My question is kaya ba nang AmP1 ang 1000 watts double magnet T&T subwoofer speaker na nabili ko sa Raon??? Rule of a thumb kasi sabi nang pinag bilhan ko nang Speaker, I shud use daw an AmP with a Power Rating of 1600 waTTs para maganda ang sound nang Speaker...
-
Sa 24 of Dec.pwd??? yun lang kasi ang available date na pwd ako maka punta sa haws mu... Any modification sa Amp1??? yung amp 3and 4 pwd sa 18 inch na T&T??? dalawang amp3 or 4??? Bridged?? Pwd kaya sa 18 inch.. ..

there are three models on westrak 120, 200 and 300watts the 300watt model requires 6 TB34 transistors on 8ohms circuit design compliant. The diff from my amp1 uses same TB34 but in double barrel config symmetry with 16pcs 8pcs 2SC2922 and 8pcs 2SA1216. and a very large transformer almost the size of welding machine and can go 2ohms straight. :o
imho my amp3 will be most suitable for your spk. The raon guys must have said 1600watts peak. since my amp3 is 800watts raw RMS output or 1600watts peak it will handle your sub as the raon guys referring.
This amp 3 is also been tested for 18inch xxx RE a P77K sub during the transhow last august at roadstar boot. believe it or not the test tone of 20hz shows an Xmax of 5 to 6 inches of excursion the bass was totally mind boggling. i wish i could afford those sub.
btw. by dec24 wala na ako sa pasay. will stay at my parents house in pque till jan.
if you can make it dec22 sa pasay mas ok. ;)

these westrack amps can use those Conrad Engineering cast aluminum heatsinks for better heat handling....
a 300 watter mono amp traffo will weigh in at least 10kgs.... ;D

decibez - florentino torres street. sta.cruz manila - tel# 7330651 look for sharon
parang meron nga westrack doon. 2-3wks ago napadaan ako.
chk out their old stocks from the 80s particularly speaker drivers. may nakamichi horn tweeter 1.6k@ yata ang laki its packaged with 6.8uf yellow poly cap. may soundtrack drivers din and some horn tweeters.

:D So sir?? Your final Word.. anu yung pinaka "RESETA" mo? What shud I pick?? Since its all TB34 package.. AMP3 bridged?? Pwde kaya ??? As to be used to my 18 inch 1000 watts Sub.. Or, the Monster "AMP1" ??? If you decide sir pilyo not watching the price tag..Which performs "BEtteR" to my speaker... THANKS!

sobra ka naman sir.
ikaw pa lang first customer ko. ;D

ha meron na ako neg feedback? o gawa gawa mo lang yan. >:(
i guess you cannot buy my amp anymore. you are now banned on my list ;D
-
HAHAHA! I min zero negative FEEDBACK... sir na mis interpret mo...HAHAha puru lahat positive....nice to know... plenty of praises in your name.... ;D
-
;D pilyo is one of the nice guys, though i have not met him personally, he had plenty of deals at tipidpc.com and is a respected member there, this much i know.... ;D
the Westrack amps, specially the high power ones, are Super Leach amp clones looking at the way they are constructed...they certeinly can use the Conrad Heatsinks to make them more heat stable...
-
My apology to you sir pilyo... I do not meant to upset you..wat i mean is "NO" negative feedback... Im sorry may mali ako sa subrang pag mamadali sa pag type.. I know a LOT of praises in your Name...Your ingenuinity is much known in your field as wat you choose... Im really sorry if I upset you... :'( :'( Sir bilis nyung magalit... You have limited patience pala... SORRY... :(
-
haha cant believe you fell for that. ;D
No harm done. And you know am one of those circuit breaker fuse that doesnt trip. lol
merry christmas. ;D
Master tony saan ba makakabili ng Conrad Heatsinks? baka pwede mo naman ako tulungan gumawa ng magandang casing for my amps. gusto ko sana mga tipong pwede na i display sa mga HT rooms. it seems wala talaga akong talent pag dating dun.

If you want a good design of Amp case pwede kita gawan (ng design ;D) just give me dimension of your panel including location of switches and knobs. I know HDM Technologies, we can make a good CNC design front panel. We can make anything you want regarding the design, the only problem is the COST
Sample ACAD design:(Not real color)

;D your amp3 pala sir pilyo.. how many TB34 ??? sa tipidpc nakita ko ang amp3 nyu P4750.00... pag dalawa ang bibilhin ko... how much???

wow nice!
heres some pic of the monoblock amp3 and 4.
possible dimensions 5h X 10w X 8d
(http://i165.photobucket.com/albums/u72/pilyo168/label/8A6J00041.jpg)
saan shop po ninyo sir?
;D your amp3 pala sir pilyo.. how many TB34 ??? sa tipidpc nakita ko ang amp3 nyu P4750.00... pag dalawa ang bibilhin ko... how much???
4 - npn
4 - pnp
total 8
plus
10amp traffo
pag dalawa kunin mo bigyan kita case. pero ikaw assemble. ;D
-
A Total of 8 TB34 in one channel? wow! sir pilyo ang power supply, gawa nyu? pwd ba ang power supply gawing 15 AMPERE??? thanks!
-
yes pwede omit 10amp traffo ko. so i-less 1k pag custom made mo kahit ilan ampere just dont change the voltage.
-
kayu lng po sir pilyo ang nag rerewind nang Xformer??? or bili pa nang ready made na? wow! may kasama pang FREE case.. tanung ko lng wat is da difference between your Amp3 and AMP2.....
-
Sir Tony... Ang Super Leach Amp gumagamit di ba nang MOtoRoLa Transistor? Ask lng ako... Leach Amp pwd din pang Sub?
-
Sir Tony... Ang Super Leach Amp gumagamit di ba nang MOtoRoLa Transistor? Ask lng ako... Leach Amp pwd din pang Sub?
yup...motorola dati bago naging on-semi, pwede kang gumamit ng MJL21193/MJL21194 kung pang bass....kung full range mas preffered ko yunng MJL1302/MJL3281....
yung leach amp magandang tumunog, sayang naman kung pang bass lang sya....pero pwede.... ;D
-
may nakagawa na bang bass amp gamit ang MJL21194 na ang power output ay 1000 watts up? DIY... Performance? wats da grade?

all i have done are 250watter leach amps....leach amps are not tiring to listen to even at high volume levels...... ;D
pang mobile ba? yes it is possible to do it, i have asked a friend to design a pcb for me using Leach's doubled barreled amplifier topology using 10 qauds of those ON-Semi devices, that's 40 transistors per channel output.
-
:) your friend done it for subwoofer purpose sir? wow!?! a monster one for the sub...how much will be spending for a mono block? rough estimate sir? hehehe a 1000 watter amp for the sub.... ;D
-
sir pilyo ilang amp3 ang ginamit sa pag test nang RE XXX na 18 inch sub???? the same 10 ampere traffo used as wat i want to buy???
-

Two amp3.
the RE has dual2 coils.
using Y rca to split the two amp3 in mono config.
(http://i165.photobucket.com/albums/u72/pilyo168/label/aaqrcasplitter.jpg)
each amp3 output connected to each coil.
therefore two 10ampere traffos per coil. now how sweet is that. ;D
for those who doesn't know what RE-xxx.
(http://i165.photobucket.com/albums/u72/pilyo168/0dcf_1.jpg)
$1600 or P77k sub
(http://i165.photobucket.com/albums/u72/pilyo168/xxx18inch.jpg)
here is a vid sample of 15inch with 6inch excursion. take note hindi pa ito yung 18inch.

-
nakita ko na sa youtube ang RE XXX na sub..ang mga MTX subs malupit din... hehe thanks sir pilyo nag abala ka pa for the pics... ang yaman naman nung may ari nang sub na pinag testingan mo...
-
Sir pilyo... ask lng ako uli ha ??? ..sorry sa pangungulit :D ... hehehe paki elaborate naman or explain kng paanu i bridge ang (2) AMp3... . Pls? :-[ thanks! :)
-
sir PILYO gd pm,
gumagawa po ba kyo nang power amp?
mg papa quote po sana ako,
mg kano po ba ang aabutin nito
300W per channel na pang sub woofer, (2 channel) will drive 800w (peak) speaker
200W per channel na pang mid, (2 channel) will drive 500w( peak) speaker
thanks for replying
-
SIR! Este boss..hehe pag nadala ko pala sa haws nyu ang westrack amp patulong naman i calibrate.. tapus baka pwedi i modIFY nyu na rin hehehe.. I know you can do mix and match sa CIRCUIT...thanks boss ;D
-
SIR TONY...ask lang ako bout da traffo... ::) pwedi bang i parallel ko ang two (2) 39 0 39 ten (10) amperes para maka arrive nang 20 amps?? thanks sir.. :D
-
For those gusto gumawa ng westrak amps i have 6 brand new PCBs of westrak.

SIR TONY...ask lang ako bout da traffo... ::) pwedi bang i parallel ko ang two (2) 39 0 39 ten (10) amperes para maka arrive nang 20 amps?? thanks sir.. :D
when i was younger, maybe like your age, i used to think that way too.... ;D
if you tell me what size your present transformer is, then i can tell you for sure, normally you can parralel two transformers if you get your phasing correctly.....
the question is, however, why do you want to do it? is one not enough? if you have two of those, you can use two transformers and feed two channels from those two transformers, meaning one transformer for each channel, what i am saying is there is another way...
why the obsession with 20 amps?
one rule of thumb for power transformers used in ss amps is that, you get the biggest one that can fit your chassis....
remember, why commercial amps can get away with smaller and lighter transformers is that, music has a high peak to average ratio as compared to sine waves which is sqaure root of two.....with music it can be as high as ten(10).....
the transformers used in the Crown PB's are phisically small....
-
hehehe ;D Salamat at naintindihan nyu rin ako... sige..ok na tu ang 10 amps... hehehe tanung ko lng is there somebody who did ROD ELLiot (ESP) Subwoofer amp na member nang PDVD Sir Tony?? How was it? Ok ba? Pwd bang i compare sa mga branded sub Amp na ginagamit nang Paradigm,Wharfedale, B&W, Axiom at iba pa.. ???
-
@pilyo...
nice! hehehe amp collector talaga kayu...May Westrack ka din pala Boss... ;D Yung sakin pala modified na ito nang mga electronic enthusiast dun sa Bacolod na mga Frends ko...Na open nila yung Yamaha Power Amp na pang Mobile Which is 300 watts..Dun nila ginaya ang modifications nang Amp...I know your very busy right now Boss... :D nakakahiya naman isingit ko yung Westrack ko sa mga Projects mu...In perfect Timing, baka sakali pwedi na.. hehehehe ;D More Power! GOD SPEED!
