TrueTone Model D-2026 series B Manual
#25

Thanks RodB, will catch myself up on that type of capacitor.

Since I now have power supply voltages that are normal enough to create some kind of sound. Thought I'd investigate why my speaker remains absolutely silent.
Injected an audio tone on the plate of the power tube 6V6GT. Nice clear tone on speaker. Then injected audio tone on the grid of the power tube. Dead, no output. Verified correct voltages on tube socket, looked good enough to me. Removed tube from socket, it looked good, then I shook it. Aha... sounded like a tinkly little rattle. Think I found the grids. New tube on order. Since I've had the chassis out of the cabinet for about a month forgot the radio had been dropped in it's past. Left front corner broken out of place. This could explain my rattling power tube and possibly others. Wish I had remembered that and checked the rest before I ordered just one tube.
