Looking for Baldwin Model 71P Organ Schematic
« on: April 04, 2011, 06:59:37 pm »
Picked up a Baldwin Tube Organ and salvaged the amp out of it after I played around with the organ for a while. It's two EL84's, two 12AX7's and 5U4. I've searched the net pretty thoroughly and no schematic. If anybody has a lead on a 71P Baldwin Organ tube amp schematic, I would appreciate any info on that. Thanks, Platefire
On the right track now<><

Good luck.  Baldwin kept their cards close to their chest.  Schematic are HARD to find.  IIRC, somebody somewhere has "some" Baldwin schematics for sale.  I ended up just gutting for transformers and building from scratch.  Baldwin transformers = good stuff for guitar amps.

Can't help with the original schematic but that topology screams Marshall 18W or Stout to me.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

OK, thanks! Kinda what I figured on the schematic. I've been looking at the original circuit trying to figure it out and I'll say they got some weird stuff going on in there. It's that real jammed up P to P and hard to see whats going where and they got some diodes in there? It's looking like it needs to be gutted and start over. Platefire
