i think we should poke some holes in it. from the looks of things, the case is going to be pretty enclosed.

the hottest points in the amp will be the fets inside since theyre pumping out the heat, without fresh air coming, the inside will get pretty steamy, may not be good to the PCB.

the xcans have this problem, with the case sealed tight, there have been issues with scorched PCBs and resistors.

i'm a pc nut too, so that part of me wants holes on the top and bootom for best circulation.

any reason why we shouldn't?

that's all the reason that I'll ever need and there's no reason why we shouldn't.

i'm thinking a future upgrade path would be to add a dact vol control, mga ilang K resistor kaya kailangan?

di pa nga nabubuo, upgrade na iniisip!

nakakahinayang naman butasan yun malinis na faceplate kung lalagyan ng vol pot sa harap. gawin na lang natin passive pre yun dact.

parang oks na yun dalawang blue led na power indicator, but it's your amp.

wala naman masama mangarap kahit hindi pa tapos yun amp.

almost there...

Doc S Tube CD Buffer...

ganda siguro epekto nyan sa sound quality ng system

docsialu · « **Reply #186 on:** Sep 12, 2006 at 09:30 PM »

just got d cd tube buffer from jojo, from my observation, it actually sort of contained the harsh highs and
put a lot of bass emphasis on my system, also mas musical ang dating ng tunog, at least for my ears, tnx sir jojo

pleasure meeting you Doc, very nice setup too.

its my 2nd nyt listening to jojo's tube buffer, i instantly put on jeanette lindstrom and patricia barber's cd which i use to find unpleasant listening to before with my setup because the highs are earpiercing with the former and the instrument in patricia barbers cd sort of came out of nowhere, but with the buffer, d music is really contained, pleasant and nice. smart upgrade for less the price

Hi choariwap,

In case you are still wondering how it was attached...

safe trip bro...

JojoD818 · « **Reply #194 on:** Sep 16, 2006 at 06:49 PM »

as promised...

ps: the psu connector for the outboard supply is idiot proof (no pun intended) to prevent a reverse polarity connection that would otherwise destroy your t-amp.

jojo, ano ba tong project mo?

JojoD818 · « **Reply #197 on:** Sep 16, 2006 at 07:14 PM »

doc,

that is a Class A 10W per channel MOSfet power amplifier. it's a clone of Mr. Nelson Pass's First Watt.

that amp consumes 200W (100W/channel) of power but power output is only 10W/channel.

docsialu · « **Reply #198 on:** Sep 16, 2006 at 08:28 PM »

galing mo talaga jo, btw, collector na ako, dalawa na stars ko, haha

docsialu · « **Reply #199 on:** Sep 16, 2006 at 08:30 PM »

ano ibig sabihin nun kung 10watt/channel per output? is that a gud thing? madadrive nya rin ba ung mga malalakas magkonsumo ng power na mga speakers like let say a dynaaudio? sorry ha la ako alam, nacucurious kasi ako eh

Ibig sabihin nun mahina lang ang output power nito. it's not a good/bad thingy, but of course it would require speakers with high sensitivity, but that won't be a problem since choariwap will use this monstrous amp to drive his Sennheiser HD650 and AKG K1000 headphones. this amp was designed by Mr. Pass with the audiophile and his/her single driver speaker in mind.

We listened to it this afternoon with the K1000 headphones, Benchmark DAC1, Audiophile USB sound card, a Dell laptop as source and a passive volume control...

hay grabe ang ganda!

we even tried using my 6SN7 tube preamp and aprub din.

tindi ng mga gears na dinala ni choariwap.
