BH5 editable schematic

[CraigB]

Recently I built an 18w chassis and made a back panel that fits into my friend's blackheart BH5 cabinet.  After awhile of playing it, he decided that he never would use the blackheart again, so he gave the chassis to me to "turn into something else".  After awhile of playing it, I decided that it sounds pretty good and chose to leave it alone, but I needed a cabinet.  Hmm.  Head or combo?  I decided to take a cheapo non-operational peavey bass cabnet, cut it shallower and reuse it for the project.  Yes, that's right, silver tolex    But it turned out pretty good and looks nice with the oxblood grillcloth I had laying around.

Since the original BH schematic is terribly hard to read without a magnifier, I decided to redraw in a .sch file, and I also included a page 2 idea for a turret board layout, which I may build someday if the PCB starts having problems.  It's obviously not to scale, so it's just more of a possible configuration that could work.

Also, it seems that if the output jack board were removed and hardwired with regular jacks, there should be enough room for a one-tube reverb or trem oscillator, etc., so I tried to open the center part of the schematic on page 1 so there's room to draw things in.

Craig,

Tell me about the 51 ohm resistor and .01 cap going to ground on the input jack?

Thanks, Tubenit

That's to help with RF issues.

Nice work on the rebuild!
I've rebuilt a bunch of BH5's with new P2P boards and iron.  It's a good size chassis for a small project.
