Uyyy...Im missing the fun.
Posted na pala...
Just got logged in today...absent po khapon sa opis, where I do most my online ek ek...
Firstly, the thread title should be...
EDREL's CORNER: Audio Toys,Transformers, Tubes, Tinkerings, etc.Edrel, please re-title it., since I wont be able to sustain it. I mean, u have many things to offer in the forum that others
have yet to discover....
Secondly, about the 7193 preamp, It was love at first sight with that horny tube...medyo kakaiba kasi sya, cute na with nice
matching specifications sheet pa raw. My instinct tells me, how could I go wrong. Tonyt, Owediah, Edrel and Alexg
like them too and offers technical services for free
, tapos may Mang Gerry 'The Tube Magnate' pa tayo na very accomodating...kaya I went ahead na...DEAL, kumbaga...
The last question is to DIY or asked Edrel... I went to see and chat with Edrel first and visited his plant (actually,
his 'audio playground'
), since we are just neighbors here in Cavite. I asked Edrel finally to commision me this
horny preamp.
I went to Edrel for his experience and resources. Edrel makes fine transformers : output,power type, chokes.They are accurately machine wounded using brand new & not recycled parts, that is, wires,cores...Added bonus, he likes Audio too and is deep into Audio tubes ( you should visit his playground & see his stash of exotic tube collections here and there, im sure dami pa nakatago sa playground nya
)...
About the 7193 Preamp Construction by Edrel:The chassis is very nice:Aluminum plate (t=?), with hardwood plinth base on the sides & back
The Layout is very clean.
7193 tubes (2pcs, national union brand). 6x5 ( 1 pc, rectifier tube, rca brand)
The wirings and points are cleanly soldered and shining.
Two inputs/1 output feature.
The parts used, Edrel only knows
...He is choosy and has lots of them in stock to choose from, dpende sa experince and feel nya).
About Initial Sound Impressions?Im not so good describing what I hear.But I liked much what I heard.
Initial Sound impression during the initial power up:
Hum and noise problem is not there, Edrel tamed them out.
The low to high frequency response is there and seems neutral to me & flat. Overemphasis in the fresponse was not observed.
The vocal quality is luscious, the instruments are airy.
The music is very involving.In short, Cute ,Maganda at Malandi sya tumunog
.
Special credit also as mentioned by Edrel, goes to Alexg for improving the circuit which I believe Edrel applied in my
preamp.Alexgs' preamp uses the OD3 tube, yung sa kin wala
.
Our Man, EDREL went back to his lab to do some more tweaks, I understand: beefed up more the psu and do the other magical tricks.
When finished, the chassis Aluminum plate will be black, sporting a chrome plated bells for the chokes and stain-finished hardwood plinth base.
Couldnt agree more with Bono,
Edrel is the ManJust pm this nice guy if u have some requirements: audio diy,transformer, parts...
With Edrel's expertise/resources, Im sure he can do a lot of favor to the local Audio Community first then who knows, with internet thing, baka mag-global pa
.
In the coming days, Edrel im sure will gladly share the circuit diagram to those who want to make their own, for this is the essence to enjoy this hobby. As AUDIOKARMA quotes, All Audio, No Attitude.
Sa mga Audiofools who posted, sure naman, u will get to listen it sa haus with matching food session, kayo pa!
My problem now is where to match it with
- i told you, love at first sight lang talaga nung una...
Might as well pair it up temporarily with my Pioneer SS vintage, SA-8800II ( with preamp-main amp buss bar connection).
Glad to know that I made the right decision, 7193, EDREL & Audio BIs
.
This is a super cool looking horny audio thing!
And its' my toy
Edrel, please explain further what you cooked for me,kinakapos na ako sa adjectives
Edrel, re-title it please, pa humble ka pa jan...post the other toys u made and still being cook-up
Danas' pre amp is just a starter...
Thanks!
Oweidah-san...pls pm Edrel for pricings.. I actually,reserved two pairs of 7193- one pair (which alexg eventually got) was originally intended for you...
Rascal...kaya di makabili ng ibang gears because of this
...now you know...
Hello Mang Gerry, please take hold of your 7193 stocks at baka may mamakyaw na naman.Please set some quantities available to give others interested a chance to try this
Alexg, year of the horns yata ngayon.Bubuhayin mo na ba ung unicorn mo, 832s???
