My friend with the 100W Impact, says it measures about 70W output, so I guess You're right!
Do You (or anyone else?) have a good scematic for an EF86 guitar preamp?
I'm working with an old (Swedish) mixer amp with EF86's in the two mic channels preamps.
The owner would like to have it suited for guitar, and it would be interesting to find a good way of keeping those EF86's. The rest of the amp is an ECC83/12AX7 stage with tone controls, and another ECC83 as PI, and two EL34's.
It has only a 50V output as standard, so I've had to change the OPT.
I don't have the shematic for it, but I'll try to draw it up. I have one of those amps myselfe too, waiting for some improvements!
