OK, I asked about this before:

I want to know EXACTLY, not partly, how to modify the 45 DRD's to used 2A3 tubes (should it become necessary).

As I now understand it:

1) You need another "C4" cap wired in parallel to the one in the 45 kit. Someone please explain how this is done or post a diagram?

2) The resistor, "R5" should be valued 3.3K ohms when using 2A3 tubes.

ANYTHING ELSE????????

Thanks,
Mark
