I am repairing a Philips radio 581A/15. The radio has been previously worked on and has a hole in the chassis where an electrolytic was once located.

Was this hole for a second 50 mf capacitor or for C3, 25 mf capacitor. Does anyone have this radio that can tell me where C3 (25mf) should be located?

There is presently a single can type electrolytic housing two 50 mf capacitors on top of chassis. Is this original or were there two single 50 mf caps.

Also, also what do the numbers on the old black capacitors represent, pico farads? Most are faded away and difficult to read.

Although my model is a 581A/15 the schematic for the 581A/15 seems to be appropriate. Research implies that this is the same or similar chassis to the Mullard MAS225.

Thank you in advance for your help.
