There have been a number of versions of the Twin, but go to www.mrgearhead.com and see if you can find what you need.

This is the schematic you want. I tried to attach it but to big (235Kb). You'll have to down load it for yourself.

Great Site for Fender info - have a browse.

Just finished a resurrection job on one of these for a professional muso buddy.

I had to replace output tubes. "Winged - C" Svetlana - matched set is the go. My buddy says the amp sounds the best he's ever heard it.

Cheers,
Ian

Default RECOMMENDED Mod

These amps have a habit of developing crackles and pops with age.

This is 95% of the time caused by half melted screens in the output valves.

DO pull the 470 Ohm Carbon resistors in the output tube screen to UL taps (4 off) and replace them with 1K 5W Wire Wounds.

Your Output tubes will last heaps longer and it warms up the amp a little. You no longer have to turn it to 8 to get that "sound" - you'll get it at 6 instead.

Cheers,
Ian
