Copeland Electronics ( PO Box 931, West Sacremento, CA 95691 ) makes a 50
watt, all tube, Marshall style amp kit for about $250. ( including
transformers )
They also make a really cool “tube mod board” that lets you experiment
with a 12AX7 in all kinds of circuits-gain stages, cathode followers (
these don’t add gain, but they do lower impedance. Cathode follwers are
often used just before the EQ circuits in many high gain, “British”
sounding amps), phase splitters, etc. All you have to do is simply plug in
various resistors and capacitors.
Copeland also makes a cap mod board that can filter out the ripple of up
to 800 volts. Great for quick design power supplies.
They don’t yet make a tube preamp kit ( low weight, high voltage
(350-450 volts, 10-20 milliamps) transformer, 4 or 5 tube mod boards, cap
mod board, chassis, etc ), but they might if enough people write and ask
them to.
Another good thing about Copeland is that they don’t seem to hype their
products like some other amp kit suppliers. They seem very
If you know of any other amp part/kit suppliers, please post the
addresses here and/or e-mail them to me. I’m having a hard time finding
transformers designed expressly for tube preamp use ( high voltage, low
current for B+, and DC voltage for tube hear ) I do NOT want to use big,
heavy, expansive amp transformers. Thanks.


Buy the Book!

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.

Playing "Help-Me" In the Style of Sonny Boy Williamson II: A step by step, note for note analysis of some of Sonny Boy's Signature Riffs

I also write Science Fiction, so you can sample some of my best stories. Also available in Kindle format.

I began collecting data about the microphones used by blue harp players before there was an internet. I began organizing it into in the late 1990s. I accumulated more stuff than I remember. This is some of it.

Harp Tab

A collection of songs and riffs that I’ve worked out over the years, plus some libraries of stuff I’ve converted to tablature. I’ve included most of the notes and instructions that helped me when I was learning to play blues harmonica.
