PCB for Bob Cordell´s KT88 tube amp from Vol 2

Bob Coldell´s high quality KT88 tube amp article in Vol 2 generated quite some interest. In fact, I had a friend build one for myself! I designed a small PCB to hold the input and driver stages, to keep te construction clean and repeatable. For those who want to build it too, here are the particulars of the PCB and the circuit it holds:

Input and driver stages

PCB layout and stuffing

PCB Gerbers

Finally, here is the complete article.

Note: one reader has produced a few PCBs; if you are interested, let me know.
