What is your Gainclone Configuration? - Page 2

Bricolo · 28th April 2003, 08:02 PM

I don't think my crappy akai test speakers are >91dB

but my cd player has a high output

Currently I'm using Sonic Frontiers TransDac (combined with a good transport, it sounds pretty good) with my Gainclone. The pots I'm using have 31 dents (Noble). On some recordings I found myself setting them 2 positions away from max. vol and on some other at half volume. It all depends on a way CD was recorded.

I plan to do one gainclone too.
I have two LM3886,4 SPRAGUE CON 10000UF/50V now.How to begin? How to choose the transformor ?
Can LM3886 use king30's schematic of 3875 forms of circuit?
Loudspeaker protect circuit need? Have asked so many questions for a while, thanks all

I don't know how much tour dac outputs, but my old sony cdp-102 (don't laugh

) outputs more than 5Vp-p on it's line out

my 100K log pot is rarely higher than 1/4th

Peter,
I removed the cap yesterday, checked the offset and was no more than 20mv. I was using a cheapo RS cap and it sounds better without it. Here's all I have left.

I can't wait to compare my current setup to the one I'm building.

take care, 20mv multiplied by the GC's gain (22)->440mV minimum at the output

I asked this before and it kinda got swamped in a discussion about the removal of resistors and what does/doesn't get grounded...

Am I to assume that everyone has pretty much done away with the RC network (0.22u, 1R) across the speaker terminals?

TIA

If your source doesn't produce any DC offset you won't get more than 30mV DC on IGC with positive input directly to ground. And it indeed opens up the sound.

You don't need Zobel at the output. Even for people complaining about oscillations, Zobel network wasn't a solution. But take care about the way you do your connections and grounding
