[sdiy] double gang variable capacitor source?

[Oren Leavitt]

Hi Nick and all,

These are getting harder & harder to find these days - everybody is using varactor diodes or PLL synthesis or whatever now...
Try ham radio swap meets, surplus electronics shops, old stereo receivers/old AM table radios from thrift stores, etc. Search the net for ham radio parts/equipment. Occasionally they appear on eBay - Whoa! here's one now:

Best of luck,
Oren

> Anyone know of a good source?  I'm considering parting out some old radios or something.  I have an eico tube oscillator (model 377)that has a big doublegang cap for sweeping the frequency range.  The previous owner used it as an lfo until finding another option.  I have since modified it with a more "playable" crank from a mobile home window.  I was thinking of making a keyboard controller of sorts to make this into a simple tube synth.. just osc and amp.  The idea is inspired by cv controllers that instead of using set resistors have pots so each key is tunable...much like some of the midi controllers.  I was thinking of doing something similar with these types of caps.  Any ideas that could be simpler?  I just know that this type of cap would cover the entire range of this beast. I'm open to suggestions. My recent time spent with older hammonds has inspired me with a bunch of pre-ic ideas. Currently building controllers with left over organ parts.
Nick
