Re: #183 Build 50w

So much (mis)information on this amp. I am using a Hammond 320-0-320 volt PT and a 4.2k Ω/60watt output transformer on my build .
I know that it should be in the 3k range. What will be the effects on the overall sound? Your help will be greatly appreciated . :!:

ellipser around input jack

I am looking at a Ken Fisher inspired schematic where there is on diagram A1A. a line with a loop around the input jack connecting to the 100k plate resistor. Not sure what it means?
Anybody?

hammond 374bx

Hi guys; my 1st post! I have this Hammond power transformer 373BX (750volt @200mA secondary) that was used in a ampeg b15. I'm wondering if/where I can use it in another build where the specs are not exactly as specified. In other words, how much can I vary the voltage/amperage without blowing thing...
