I have finished my Universal Pre-Amp build and am very, very happy! I have two questions.
1) I believe this is just a happy accident. My front piece of plinth wood did not have a hole pre-drilled for the volume control. Since I use it with an amp that has volume control it didn’t bother me, so I just ran a continuous wire omitting the volume control. My question is, does this hurt the amp or tubes since it is being ran at full power all the time?
2)In picking out a DC power supply for the 6V & 12V power supplies. What is the minimum and maximum amperage that should be supplied by the power supply.
