Dear Members:

I am restoring a Majestic Model 70, with an 7P6 Power Unit which is giving me

problems!  Does anyone know the Ufarad values of the 6 electolytic capacitors

used in the "Condenser Bank " ??  I know they all connect to B-

They're paper, but you could use electrolytics.  The schematics are in Rider vol.1, two variations.  The older one uses values of 2, 6, 2, 2 and if there's a bypass across the 71A cathode resistor that is 1 microfarad.
