SR-45 Paramour II Up and Running, but ...

98.165.173.1

I finally got my SR-45 mod done. The original Iron and Cap mod version had an annoying hum that I was never able to trim out. The hum is gone.

I know that the SR-45 mod produces less power so the volume needs to be cranked a bit, but how much? I normally listened to them at about the 9 o'clock position on the FPIII Extended. Now I have the right channel at full volume and the right channel two clicks less that full. Even at this level it isn't as loud as I would like. Is this normal? The speakers are 100 dB.

Here are some voltage readings:

Test Point L-Ch R-Ch

A1 2.5 2.5
A2 317 267
A4 2.5 2.5

B1 316.8 317
B3 7.98 7.95
B4/B5 6.3 6.3
B6 210
B9 9.39 12.63

T9 216 285
T11 211.5 285
T14 316.8 286

Thanks,
