Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Audiophiles have become more unreasonable.......

Dan,

I built a similar topology only using (2) halves of a 67N7...Both halves loaded with a CCS, RC coupled and standard self bias on the output. I found that Triode strapping the output provided too much damping so I went EL34 Pentode with a solid g2 supply and a PIO cap bypass...The result is a wide sound stage and rich Mids and good bass response driving a fe207s in a voight pipe inclosure...I have not exposed this amp to any difficult loads yet ...but I think I achieved most of my goals.

My goal was too provide a design that did not break the bank on the output valves and still provide an SET eloquence...
