Home-made Tube amplifier

  1. Mar 15, 2007 #1
    Hello All,

    I'm working on a three-channel tube amplifier for some experiments I'm doing (and later on, my keyboard :biggrin: ) and I was wondering if the nice people here could give me some tips for the circuit construction.

    I've already ordered a bunch of 6au6 tubes (because they were 50 cents each and within my power requirements) and a nice transformer from eBay here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=ADME:B:EOIBSAA:US:11&Item=270098160430 [Broken]

    I'm looking for the simplest possible circuit diagram for the power supply and amplifier stages that I can find. So far, I've found these three links:


    But I was wondering if anyone here knows of any other really good, intuitive tutorials talking about how to make one (and what each part does). As this is as much a learning experience for me as a project, I really want to understand what I am doing besides just soldering a bunch of parts together from a circuit diagram.

    One of the best tutorials that I have found regarding how each component performs in circuits is Dave Funk's Tube Amp Workbook.


    It is comb-bound so it will lie flat on your table or desk, and it has all kinds of handy reference material, including a good collection of Fender amplifier schematics.
