Got the first one 99% done. Should have the 2nd wired later this week.
Poseidon Rev2 board
Hammond 300BX
Hammond 1650RA (easy wire version)
Hammond 156R choke
Curcio Audio ST7U-B PS board
Hammond HWCHAS1310BK Chassis
Waterjet top plate (CAD available, just ask)
mA Meter (currently have a VU meter in its spot)
Triode/Pentode switch
Sounds great. No hum, good power, and good bass. Took a day to debug. I'm not an electrical engineer. Had to swap F&G and replace R16 with a 56K in the end.
Went with the 300BX to get an extra 5V. Used a simple voltage doubler from TubeCAD to get 12VDC. Original idea was to use that to power a VU driver and a VU meter backlite. Way too much distortion with that hooked up. Since I have the hole I'm switching it over to a 100mA backlit meter. The bouncing VU meter would have been cool though.
