Bugle 45

Thanks. See the pics, one from each mono. They are very hard to see, and my soldering skills leave much to be desired. It may be better to look at the sketch a few posts back.

Also, perhaps the steps below may help:
1) Tie 1 and 7 together.
2) One of the two heater wires goes to both 4 and 5. The other heater wire goes to 9.
3) 1 Kohm resistor between 1 and 8.
4) The 0.047uF resistor goes to 8. The other end goes to the grid of the 45 tube socket.
5) 1 Kohm resistor goes to 2. The other end goes to Input+.
6) The 27.4Kohms and 10uF SCR go to 6 then to ground.

With vintage metal parts such as tube socket terminals or PIO capacitor terminals, I use a small file to gently polish the metal terminal before soldering. This makes the solder flow more easily.
 
Thanks, your written description was very helpful especially #2. It looks like the heaters are connected in parallel.
Would it be Ok to share one filiment transformer for both SRPP channels if built as a one chassis stereo amp?

I think so according to the schematic. However, I am not an electrical person. Others may want to chime in.
