Strange conversion

[Stuff4bikes]

I picked this up last night, it's a Baldwin panoramic tone cabinet....
Cant find a schematic for it but looks like it has 3 seperate reverb units
With 2 12ax7's and a gain per spring.
8-12ax7's
2-EL84's
5U4
In total.....
Anyone familiar with this?

It's called a necklace reverb. If I had that unit I would try to fix it as is. The electronics chassis is nothing special but the entire unit probably is.

i have a schematic for the single "delay line" unit that was inside an organ if it would be helpful in diagnosing the reverb part. you may be able to find a schematic/service manual for the whole unit if your googlefu is good enough

How can I play guitar through it with out destroying it? I can turn the unit on and tap the cabinet and hear the springs through the speaker, not sure if that means anything.

You'll need a schematic to figure that out. If you post the model number of the unit maybe we can help find some more info. Maybe take a close-up pic of the data plates on the amp and the side of the cab.

these are not your exact model (i got them as a reference for a conversion of the amp and reverb unit a friend picked up to send to me), but they should be helpful (yanked them from photos in a reverb listing because the schematics seem harder to find than hammond organ schematics)
i'll do some more looking though

Looks like mine may have a seperate pre amp module. Thanks for all your help so far....

'Necklace' is the early Hammond. The Baldwin saggy-thing is quite different. It does not pass baseband audio; audio is modulated on a supersonic carrier, passed through spring, and demodulated back to baseband audio. You need both parts.

I will probably put it away for a long term project then.

audio is modulated on a supersonic carrier,

Thanks, I was almost loosing sleep over the amount to tuners in that thing!
