    I understand that this is a 90v power supply which can be used for 7 pin tube radios. Thanks for this diagram. But I could’nt understand the value of R1 which is 330E. PLEASE GIVE DETAILS.

    • Hi,

      The power supply can b used for high voltage and low voltages, Kindly replace R1 6.8K/2W for 90V DC supply, its mistake, 330E is suitable for low voltages like 5-6V. Thanks reminding me a mistake.
      Regards,
      Raj
