I was given a basket case Philco 40-180 chassis. I replaced the electrolytics and signal caps and some resistors. I can get a bit of sound through the speaker, but not any stations. The Rider schematic has some voltages, but not a voltage chart.
Does anyone know where I can find a voltage chart for the 40-180?

I took some measurements, maybe someone can confirm if they are correct or not.

41A: P 177VDC, G2 180VDC, G1 -11.4VDC, K/G3 0
41B: P 177VDC, G2 165VDC, G1 -11.4VDC, K/G3 0
7C6: PT 148VDC, GT -.82, PD2 -.62, PD1 -.32, K 0
7B7: P 180VDC, G2 81VDC, G3 0, G1 -.6VDC, K 2.4VDC
6J8: PHP 175VDC, G2HP/G4HP 81.6VDC, GT/G3HP .1VDC, PT 144VDC, K/G5HP 2.4VDC, Grid Cap 0
1232: P 160VDC, G2 95VDC, G3 -.02VDC, G1 -.9VDC, K 1.9

All heaters were 6.75 VAC

I tried injecting a 2.8v sine wave into the volume control wiper and got only 6.8vac across the speaker secondary. The speaker and field coil ohmed out OK, but the sound was low.

Tried pulling one of the 41's b/c I was suspect of the G2 being higher than the plate, but it didn't seem to matter.

Finally, I really don't care about the SW band too much, just AM broadcast. Can I remove the push buttons and bank of coils and padders and still get AM reception?
