Just thought I would post some photos of the latest build. Had chassis done last week but finished cabinet Saturday. This is a Fender Princeton Reverb circuit with some changes. As usual with me, form somewhat dictated function on this one but I'm super happy with it. It's the second of this circuit that I've built in the past few weeks. I had a pre-cut Princeton chassis (straight, not angled) but a power transformer with voltages that required a solid state, not tube, rectifier. So with one extra octal socket, I decided to have fun. Decided to put the tremolo/PI tube in the last of the three octals (other two were the 6V6s). Since it's an octal hole, I ended up using a 6SL7. With the PI/tremolo on the octal, I now had one extra nine pin hole. What to do with it? Decided to add another channel, and voiced it more like an early Marshall. I only needed one triode, so I enlarged that first nine-pin socket to octal size and put in a 6SF5, which is the octal version of one half of a 12AX7. I ran these two triodes to a switch. One position, stock Princeton. The other, the new channel. Single input jack. Other changes: Lar-Mar master volume, bright switch on the treble, mid pot, and various things to slow tremolo and decrease reverb attenuation and noise. Added a parallel D node, on which I put the early gain stage plates. The amp sounds fantastic. And the Tolex is great stuff ... very sparkly vinyl that I got for a very reasonable price on fabricempire.com. Thanks for looking! I will probably build this one again.
