Ok...few questions. Ive biased my own amps before and always, but this is the first amp with 4 powertubes. I use a bias meter, but it only has two tube sockets, not 4.

Can anyone write me a detailed process of biasing my xtc, including trim pot location?

I will write you a bogner bias ballad as a thank you gift.
 
Invest in a bias-rite, run em at 32.5mA

What kind of EL34s you got?????

BE CAREFUL AND DON'T DO SHIT TILL YOU KNOW WHAT YOU'RE DOING!!!
 
Bias pot is in rear bottom, need to partiall slide the amp out of the rear of the headshell about 4" or take it out altogether. I turn my head on its side and slide the amp rearward about 4" until I can see the bias pot inside and have access. It's white with a slit for small screwdriver, say bias right next to it on the board. Bias to 30-32mA seems about right for most although a few folks like it at 29 or so. The power tubes are set up in pairs, tube 7 and 9, then 8 and 10 but there is only one bias pot so get em as close as you can. Be careful, good luck
 
Is it any different than anything else? Seems like my carol ann...
