Teletone verticle size

[timmy]

Ok, recapped, that's it, and it's I think 1948 teletone leatherette without the cover, 208 but what 208 no one knows. Comparing to the 149, 208, 208tr, none help this set at all as there are so many differences from mine to all the schematics out there. I'll figure it out, thanks.

Merged the several threads about this set into one. In the future, only create ONE thread per topic, please.

I'd imagine that they kept the vertical stage fairly standard across models...Trace your vertical stage and compare it to the schematics of all listed models that use similar vertical stage tubes to yours...If the vertical stage matches (or is very close), and uses similar B+ voltages, then all the tube base voltages on the vert section of the schematic should be used as references and compared to those in the set.

What's kind of odd is I compared the teletone tv149 voltages and the tv208 and they don't come close and the tv208tr voltages I don't have as I only have the schematic not the resistance and voltage charts. This verticle problem is minor I'm sure because everything is working fine except turning the size pot it stops filling in then gets a white line across the top almost to say it went over some limit. The pot I checked and it's good and also the resistor from the pot to the tube. I have 410vdc at the size pot but don't know if it's the right voltage.
