What kind of mods would I have to do to get more clean headroom out of it? I listened to the demo and it sounds awesome!.. just not much room for good clean tones.

@HellBent1337 #1 use a hammond 125ese output transformer #2 raise the pre amp plate voltages #3 use a very efficient speaker ... there is not a lot you can do with a single ended 4 watt amp ... just like you cant make a motorcycle a good dump truck LOL

what brand of power capacitors did you use for the 47 mfd? Also, was it at 500 volts?

[patfurlan]

@jonbehert the amp runs at 300 volts but I used 450 volt caps for all power supply work

@eRealist Stupid Question. Did you post part II of this video? I cannot find it.

[patfurlan]

@eRealist because I had enough room to work & it was much faster to flip it down again and listen to the change

[eRealist]

Why didnt you unplug the board and get it out of the case?
