TO-3 SYMASYM

Brianco: your questions are always welcome ;) .

I do not use a Pre-AMP / Buffer at all.
(You have the builder's manual! Take care of the values of resistors R29, R30 and R36!)

I use a source-selector (a small DIY relay - PCB: my sources are CDP, MP3-Player and DAC) and the Lightspeed - Volume-Attenuator
(you can take a "good" dual log. potentiometer as well).

Regarding the heatsink:

I use an ALU-L - profile: 40 x 40 x 4mm.
This heatsink:

for example, is very well suited.

Best regards - Rudi
