Stromberg Carlson AWP-8
#39

So, tonight I reassembled the volume / switch and powered it up.
I immediately got the BC local station and some more when touching antenna input with my finger.
I also got activity on all but two SW bands of 16m and 19m.

The voltages across filaments were a bit off, especially that of the output tube. I brought the resisrors paralleling filaments to proper values using some parallelled resistors and the voltages cane closer to the target. Off a bit, mostly at the output tube where it is 3.1 V instead of 2.8V.....I might check the current, but then on some tubes the voltage is exactly where it should be, so I'm not sure this is what's at fault. The 620 ohm / 15K divider's resistors are very accurate.

I think the deviations are small enough for me to leave it be. Also it might be different with battery power.

Speaking of the selenium, the voltage after it (I measured it at 117V which seems to be the nominal voltage) is 119V with 125V shown at the sch.....to me (am not experienced with selenium rectifiers) it seems OK and the part is not really hot. Again, I will only use it rarely, I fully intend to buy two more batteries for the second TO and this one.

I seem to rip the bandswitch cord inadvertently (got jammed and I didn't notice, and it snapped). Seems to be a regular green coarse thread.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
