Traynor YCV15Blue - adding bias adjustment
I'd like to add manual bias adjustment to my Traynor guitar amp.
The service manual that includes the schematic can be found here:
Any help would be much appreciated as I honestly don't know where to start. Suggestions of values as well as which resistors to change and how to wire the pot would be much appreciated!
I've just ordered new tubes and would rather not nuke them by making a mistake.
Thanks in advance,
:cop: Moving this to the instruments & amps thread..
Sorry about posting in the wrong place. Didn't realize we now have a place for musical instruments. Amazing how the place keeps growing and growing...
While I'm asking for help, the other thing that I'd like to do to this amp is install a switch to be able to select between triode and pentode modes.
Where to install it would much appreciated.
For the record, while I've done lots of solid state amp work, I know nothing about tube amps and am trying to learn.
Thanks in advance for the help,
