Various Schematics, Articles, and Data Sheets

The Peasant's collection of miscellaneous technical information and diagrams.


Garnet Swinger Guitar Amplifier.

This is the amplifier The Peasant uses for making music. Synthesizers sound much better through tubes!

Schematic

Line-Powered Tube Amplifier.

Here is a small mono tube amp that The Peasant picked up cheap at a flea market. This looks like a good unit to drive a reverb. Note the selenium rectifiers and lack of any power transformer. If you have any information about this unit and from what it was removed, please send me a note!

Schematic

Tube Circuits.

Here is a DC amplifier circuit for raising lower solid-state synth voltage signals up to tube level voltages.

Schematic


Here are a couple of tube flip-flop circuits.

And a tri-state flip-flop circuit. Thank you to Danial Stocks for this circuit!

Schematic


SN76477N Gated Noise Generator Circuit.

Here is a circuit The Peasant put together to generate the "snares" sound in a percussion synthesizer. A basic trigger and output circuit are included for stand-alone use.

Schematic

Diode Matching Circuit.

Here is a circuit for matching diode voltage drops at different currents. Useful for building balanced modulators.

And for you beginners, a bit of a humourous rant from Harry Bissell regarding the importance of getting an oscilloscope for troubleshooting, as well as a good explanation of decoupling. Thanks, Harry!
