are all the plastic ties for resonance control?

what type pots are you using?

do you find one transformer adequate?

amazing work... i don't know how you do it. I've done point to point work on all the tube equipment i've built, but i've had a nice wiring diagram to follow

thanks for sharing!!

Thanks Duck- Twacy!

It is pretty much standard, a few mods to suit parts available, the junk box and my own preferences and not atleast to fit everything into the rather small enclosure (224*283*40mm):

-The regulator is floating, ie no zeners. ~55/50V unreg./regulated. C101/102 is 10000uF.
-Gain is ~12dB, but easily changed.
-No P1 & P2, 22,1K ohms fixed resistor instead. Same goes for P5, currently 390 ohm.
-P3 & P4 is 10K ohm.
-R1-6 is Caddock MP930 (750/1500 ohm).
-All electrolytics are bypassed with 0,47uF Rifa MMK.


I guess the pictures pretty much tells the rest of the tale...

Oh, I almost forgot: The sound is:
