Forward! The cab thread https://www.tdpri.com/threads/curbside-shelf-to-princeton-reverb-style-combo-cabinet.984670/ is done and old enough that it no longer publishes to the TDPRI home page, so it's time for the amp build thread to take over. My local hardware store stopped carrying the epoxy that turns 'metal' colored and replaced it with this stuff that dries translucent. All the extra holes are filled. Open octal slot is for a 50/50uF-500V caps and the larger slot will hold the PR-type 40/20/20/20-500V caps. Main circuit board and rectifier daughter board and drilled and waiting for eyelets. I tested the power supply and the heaters are functioning properly. I'm seeing -345-0-345V unloaded on the high tension circuit, That is more voltage than I'm happy to see, and so I'm not sure what my power supply is going to look like yet. Maybe a 5E2 Princeton / 5F4 Super -style choke smoothing stage before the OT primary, and maybe a dropping resistor in that place to get the B+ lower. 5E2 / 5F4 choke Dropping resistor Possible presence circuit, slightly different power supply *** I also would like to implement a 5F4-style Presence control, but am still reading up on how to implement that. If you have any thoughts, please do share! Parts order submitted! Edit: delete that extra 220k resistor on the reverb recovery/ v3b grid leak -- that's a holdover from a schematic that needed channel mixing emulated like Robrob's blackvibe. I just realized it's not on the PR and doesn't belong here.
