Hey, i have a Peavey 6505 head and if i pull two power amp tubes it says somewhere that i have to rematch the ohm impendance or something like that. Can someone clear that up for me and tell me what i have to do?

Thanks

If you pull two tubes, you lower the volume about 12%. Usually not worth it IMHO. Look into attenuators.

If you want, pull two output tubes (probably inner tubes), and then plug your cab into the next lowest ohmage on the amp.

EXAMPLE:

Cab: 16 ohms? Put into 8 ohms on amp.
Cab 8 ohms? Put into 4 ohms on amp
Cab 4 ohms? Put into 2 ohms...prolly don't have that though...
