I recieved many E-Mails regarding a post about my amp kit, I thought it
might be easier to respond here.
First the cost of the kit is $599.00, this is for a complete amp head kit
with cab.
I expect the power trannies to arrive mid Oct. so kit’s will be available
by Nov.
I designed this amp as a primer to tube amp builders.
It’s a 4 tube 45 watt EL-34 output class A/B fixed bias amp.
Since it is a primer I decided to use a little differant topography, in an
attempt
to show the use of other than typical tubes.
The input tube is a EF-86, for those not familiar with this tube it’s a
high gain
pentode, rather unique sounding, not your typical 12AX7, also it will tolerate
higher inputs, making it handle stomp box inputs very gracefully.
The tone stack consists of Volume, Bass and Treble. which then enters a
non negative feedback long tail phase inverter.
The output are two EL-34’s push pull fixed bias.
The output tranny has 4,8 and 16 ohm taps .
I have attempted to make this kit simple yet original, easy to build yet
challenging,
and use the highest quality componants and still keep the price resonable.
I hope this answers the many questions posted.

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.

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 JT30.com in the late 1990s. I accumulated more stuff than I remember. This is some of it.
