Very nice! (and very tight!)
How does it sound?

 

[jalejos]

I like it sounds more like the version with toroidal transformer.

 

[ssanmor]

Excuse me but I don't understand you very well from your post: do you mean that you like the version with SPS80 more, or that you prefer the version with linear power supply and toroidal transformer?

Thanks!

probably has lot more doing with ucd amplifier, don't you think so ssanmor?

Probably it's too early and my brain isn't too awake yet, but what do you mean exactly?

Hello,
Could you ellaborate a bit more on this? What are your impressions and the differences you find?
It's strange because our users usually prefer the sound with our SPS80 than with linear PSUs. Perhaps the system can be optimized and we can help you doing so, perhaps not.

Hi!

Whole casing is made from plexi glass. It is just glued together with superglue.

p.s. Sorry for so long reply but I had some problems with my previous account.

This one is 3122D2 on breadboard. Tested it with 15V adapter supply and 8oham stereo speakers. Very good voice output. Hope to convert to PCB soon.

I know that much...

Did you use modules designed/made by somebody else or did you design these?

Is there any additional information you can provide?

Thanks!

TA2020 from arjenhelder_electronic on ebay, it is his MkII PCB, but the input caps have been shorted out and the input ground is connected to the bias cap pin 14, i.e. it has been modified for a DC-coupled input. The mods are under the board so the PCB looks standard in the pics.
