Triangle Wave Oscillator 3 channel Synth Project

via this auction
"Here's a great 3 channel Triangle wave oscillator, onboard isolated powersupply (12vdc). The case was a new Radio Shack Video to RF converter, but I gutted it, modified the power supply to get 12 volts DC to run the 3 channel circuits inside it. As you can see in the Scope photo's, the 3 channels has thier own adjustable settings. 1, 2, and 3, outputs are RCA on the back. Switch for on/off. Nice and clean outputs. This will work great for adding LFO's to other synth's you might have or just use it to control other projects. Case is 3 x 5 7/8 x 1 3/8 inches, four rubber feet under the case. Nice and compacted. Runs on 120Vac only!!!!!!"
