Ok so if I wanted a little more bass (I know am a heathen to add more bass to a this champ style of amp) what would I change the 0.0047 to
Also like the tone removal idea...so would need a 10m resistor...what w rating
You can't really boost bass by altering the tone control, you can only cut less bass. Experiment with small caps, say 0.0022 to start with.
You could also try increasing the size of the cap on the cathode of the second valve stage. I can't read the value (I suspect it is 0.68 µF) but it is the polystyrene cap second from the right in your photo. Try up to 20 µF.
You could also try increasing the value of the coupling caps, although without knowing their values (I can't read values on the schematic), then I can't advise whether this will help or not.
To disable the tone control connect a 10 M resistor between ground an the 0.0047 cap. Then wire a switch to short out the 10 M resistor. Any 10 M resistor will do — to dissipate 0.25 W in a 10 M resistor would require 1.5 kV across it!!
A word of caution though too much bass and you might encounter the dreaded blocking distortion.
