Hi All,
I'm just about at the stage of putting together my SSE, I have a few quick questions for you guys first though.
I've got a V2 board, which appears to have a couple of components not present in the schematic; specifically D3, D4 and TR1. D3 and D4 lead to pins 4 and 6 on the rectifier tube, I'm not sure where TR1 goes. What do these components do and are they required?
I was inspired to build an SSE by this post, I really like the symmetry in this design and would like to do something similar. The guy who built this has wired point to point, whereas I'm using the PCB. What wire gauge would you recommend for wiring the tube sockets to the mounting points on the board? I'm guessing that with the frequency response on tubes, I should go as thick as possible as capacitance isn't likely to cause any issues?
And finally, the design above appears to use two identical capacitors. Would I be correct in assuming he has wired two 50uf motor run caps in parallel as his auxiliary capacitor? If so, would two of these be suitable?

Hello bk2018,
here are my notes collected from various posts about D3/4 and TR1.

here are my notes collected from various posts about D3/4 and TR1.
- 2 diodes are added (D3 & D4) on PCB. Use 1N4007 UF4007 diodes.
- A place marked TR1 is also added, which semms to be a GE CL140.
- Starting a SSE build

- SSE first build, need part clarification (help)
