Looks Really nice Peter. Good Job. I have very simular heat sink's too. How do they sound ? What speakers are you driving ?

I'm using full range drivers (Fertins 20 EX in an open baffle arrangement). The sound is very good.

I'm getting the transformers from here: http://toroidy.pl/

I was writing about it previously in my AS thread. I compared those transformers to Plitrons and prefer them. Since shipping from Europe is expensive, I use those transformers only for my personal projects. They are still reasonably cheap, well made and lead time is short.

All the high power resistors are Mills, the other resistor choices were dependant on what I had in stock, so all 220R and 22k are Caddocks, 10k input series is Vishay S102, there are few Holcos and Mills.

I posted some detailed pics here: http://www.diyaudio.com/forums/showt...617#post968617

Yesterday I bypassed Jensen output coupling cap with teflon V-Cap and it 's an improvement.

thanx again Peter for all the answers and links .

the last questions : what value of the teflon cap ?

Have you experimented with other power supplys ?
CLC ? or CRC ?

Can you please share a little bit more your findings with
the elcos and resistors in comparison to other types
or cheap parts like the panasonics ?

thanx in advance

Jürgen

Can you point me to the thread where you describe your opinion and findings about the sound of those Fertins if the one exist? I tried to find it but couldn't.

I don't think I did it, but so far those are the best drivers I had. Check back posts of bcherry and dice45 on Fertins, they would be pretty much in line with my impressions:

Fertin project - calling all open baffle experts
Full Range Drivers
