My JLH
It looks quite ugly compared to other things in this post, but it really sounds good!
It's my JLH, version "2003 update" (I think that's what it's called)
with CapMult, A970 input T, A733 ccs (maybe not copletely stable), C3421 driver, 15003 output T.
Works at 24V and 1,25A quiescent current.
Made it all by myself, pcb from Eagle and toner transfer, and many parts from wrecked equipment. Very proud.
It took me forever to tame the last buzz, and I should just have followed the "earthing" instructions...
But since yesterday I have my own class-A, and it is sweet.
Many thanks to diyaudio!!

Bee, you need to use the attach function, for us to see the picture, or upload it to an online host....if you want to use the tags like you did.
At the moment only you can see that picture, because it points to a file on your PC...
The rest of us only see

My JLH
...and the transformers.
These come from eBay (the guy still sells some of the same).
I would appreciate an opinion about these transformers.
I took them because they were cheap and I use them for my prototypes. They give 19-0-19V and are "labelled" 160VA.
I have them on a separate "piece" and I'll replace them with "better" tranformers as soon as I get a good deal.
Or are these any good?
* * *
Next in the list: build a GEM.
The better of the two (JLH or GEM) will go in a high-WAF enclosure, the other will play music too, but in my own working room.
This JLH is sweet, but I could do with some fuller medium-bass when playing rock; for jazz and classical I can't stop listening!
