Hammond Organ transformers?

ebartlet · May 16, 2009

Hey everyone, I'm parting out a Hammond L-111 and there are a bunch of transformers on to of the tone generator, I was wondering if anyone has found these transformers useful for any other application, before it hits the scrap bin?

I think the ouptut transformer is a regular PP El84 transformer

And the psu is probably useful too

I parted one of those, not sure about the exact model, yes the amps there are pp el84, however the speakers were 16 ohm, so the transformers are like 7k:16.
Power transformer can definitely be used for something...

Yes, actually the whole amp chassis could be made into a guitar amp pretty easily, which I'll do or sell to someone who wants it. What I'm referring to are 40 or so transformers on the top of the tone generator:

Without seeing it I'm assuming they are inductors for tuned circuits for tone generation. Possibly multi-tapped.

Thats exactly what they are. Some frequencies come right from the pickup, some have a capacitor, some have a coil, and some have both. They can be useful for replacing a missing tone, if you have an open coil. Although they are certainly NOT all the same, so each coil is only optimized for its intended pitch.
