Echophone S-4 Help Wanted
#5

Hm-m-m. Voltages did indeed increase, but the problem is that the B voltage is already too high. The 245 plate should be some between 150v and 250v. It's 345v at normal line voltage. Except for filament voltages, a quick check seemed to show all other tube voltages were too high as well.
