In case you are managing NOS valves, I wouldn’t worry about it a lot of, as NOS valves can very typically just take bigger voltages (Mullards are rated approximately 400V). Existing production valves are generally rated as many as 300V, and you can commonly exceed this by about 10%.

It is also wise to print out a schematic with the amp you're focusing on and document any modifications you've got designed. That way, if you do must take the amp to an amp tech, you could give them a schematic that properly demonstrates the circuit. The schematic with the AC15CC is presented below.

Then mount the 250K tone cut pot in the hole which the reverb pot used to sit in, and operate the wires close to to where by the tone cut resistor was on the main PCB board.

Any time you appear within you’ll see two prolonged PCB boards. One particular board sits along The underside on the chassis, This is actually the most important PCB board. Another PCB board is mounted vertically, powering all of the Command knobs and it is known as the ‘pots board’ as all the potentiometers are mounted to it.

Do not forget that new speakers have to have time to interrupt in. So If the amp is new, give the speaker time to interrupt in before you decide to make any choices about upgrading.

pondering if any person will help: I am wishing to swap the caps in my AC15h1tv. But I actually don’t recognize which caps I should really change. The schematics are at: www.*blue*guitar.org/new/schem/vox/ac15htvh1_handwired.pdf could any person help me out? I will be really grateful

There are actually even mods the fall a connector completely, obtaining threaded atomizer screw instantly onto the tube.
