Top job Doc.

On my wife's side of the family there is an old valve small organ that isn't working and needs a new home and wondering how hard it might be to fix considering it may date back to 1960's?

Oh, should mention I know Jack $#%t about serious electronics which only adds to the degree of difficulty taking on a project like this. Any help or advice would be much appreciated.

Cheers, Waz

If you can find either a service manual, or some circuit diagrams on the internet for the organ, it might turn out to be fairly easy to fix depending on what's actually wrong with it, it might just be a case of replacing a valve, a resistor, or capacitor that's gone bad in order to get it working again, hard to say, what is the organ doing and not doing?


A lot of those old 60's organs are still worth fixing, and if it's a well known brand of organ, like Hammond, it could be worth a lot of money if it's in working condition, or restored to working condition.

I wouldn't mind scoring myself a nice Hammond L-100 organ in working condition, the organ player in Uriah Heep played one, the Hammond L-100 used all valve circuitry and electrically driven tone wheels to produce it's distinctive sounds.
