Test #2.....

SET Asylum

Single Ended Triodes (SETs), the ultimate tube lovers dream.

Well I've got the Version #2 of my 26-26 DC 45 amp up and running last night. For now I'm using the Hammond 125ESE's for OPT's, I'll wait until I get all the voltages tested and ran in, before I switch to the E-P OPT's.

I did notice the Version #2 amp isn't as quiet as the Version #1 amp.
Ver.#2 has a Hi frequency buzz that come in and out( Off and on ) of both channels. At turn on the buzz is louder then after a minute or so it gets quieter. At 3/4 volume you can hear a buzz in the background ( On and OFF), but never goes away...... With Ver.#1 I get a lower buzz at startup but after a minute or 2 it really fades almost completely away...

I blame those little DC to DC converters for Hi pitched buzz on Ver.
#2. So after running the amp most of the afternoon at a nice volumes
the buzz is still there, so I think I'm going build 2 more LM338
Adjustable boards and ditch the little DC to DC converters.

After that it's just a matter of switching the Electra-Print OPT's over to the Version #2 amp and put the Hammonds on Version #1..... Then the real tweaking starts on version #2........I got the ver.#1 where I was quite happy with it's performance,. I hope Version #2 turns out even better !

Here's Ver. #1

Onward !
Willie
