Default Re: Vintage Radio and Phonograph cutter schematic

Thanks Lawrence... jeez that is a lot of DC in the cutter head? or that 25k resistor will reduce this to the operating voltage if the crystal cutter...?

The crystal cutter head operating voltages is 75V according to the Astatic X-26 manual

Thanks again..

Missing question: could you please let me know which manual you referring to? I have few pages of this unit and on that the 6v6GT plate is 240V ? many many thanks!
