THERE ARE FOUR 2MFD CAPACITORS IN THE
POWER SUPPLY. THE DRAWING DOES NOT INDICATE PLUS AND MINUS. CAN SOMEONE TELL ME IF THEY ARE ELECTROLYIC OR REGULAR CAPACITORS??

Hi Chris,
Power supply capacitors are electrolytic. Usually, any capacitor rated at 1 MFD (microfarad) or higher will be an electrolytic.

There are non-polarized electrolytic capacitors available, but they are not found in the power supply.

Look for any indication of a common connection on one side of the capacitors. (There may be a label in the schematic for B-.) If so, this will be the negative side.

If one side of the capacitors are connected to the plate or grid on the tubes, this will be the positive side.

Hi Mark
Thanks for the info - I used (4) 2 MFD electrolytics in the arborphone - came to life after that - sound a bit muffled though - a trait of the TRF sets I guess - Many thanks again - Chris
