Cossor 343 Ganging Oscillator (Wobbulator)
I've just finished restoring a Cossor 343 wobbulator aka 'ganging oscillator.' It was a pain, given that the circuit diagram had nearly all of the component values missing + the small value capacitors were just partially-melted lumps of wax! If anyone's interested, details are at https://app.box.com/s/kvj87rrhl3fum6jpnzyzh10kkfacvvvt

Re: Cossor 343 Ganging Oscillator (Wobbulator)
Well done, Bill. I had one of these once, but passed it on to another Forum member for restoration.
The photos and circuit are great. If you get time, why not write up what you did and post it here as a Success Story?

Thanks Phil 'Success' isn't a word that I would normally associate myself with, but I'll give it some thought!

That looks pretty successful to me!... Along with a nice re-creation of a classic application.
