Hi Guys -
I'm restoring a 1967 Frank head. I've discharged the caps so that I can safely begin the project. The inside of the chassis is pretty grimy with a lot of caked on, baked on dirt. I could probably disassemble the entire amp, but just wondered if there were any quicker ways to accomplish chassis cleaning. Vacuuming won't be able to remove 40 years of gunk. Any hints?
Thanks,
Bill in MPLS

Hey Bill, welcome to the board!
If there is a lot of cigarette smoke and kitchen grease built up in there, you'll need a spray cleaner like Fantastik or Formula 409. I spray some on a rag and then start wiping out the larger surfaces. Then I'll use moistened Q-Tips to get into the tiny areas. Don't worry too much about getting the boards wet, as long as you dry them out before you power the amp back up.
If you need to remove or loosen any of the boards to get at different areas, I'd recommend taking a few photos of the chassis before you start in case any wires should come loose or get un-hooked while you're working. At least on a Frank head, you don't need to remove all of the pots to get the boards loose.
The worst case I've ever cleaned, was a 200B head that was flood damaged. There was 1/4" of mud dried in the bottom! I ended up removing all of the electronics and then I power washed the chassis to get the mud out.
Hope this helps,
Bill
