Magnavox console radio/phono assistance

The 30 MFD at 25 v cap section is the in the cathode circuit of the output tubes...it should be paralleled by a 100-200 ohm or so resistor. If this cap is shorted you will have no bias voltage on output tubes, causing them to overheat.

If this cap looks bad, you need to replace the entire can...you can install a terminal strip and use modern electrolytic capacitors, making sure polarity is correct. If one cap in this can is bad, the others likely are too or will shortly go bad.

The other caps in the set are paper caps, non-polarized. I always like to replace all of these, you can replace them with Mylar or Orange Drop caps of equivalent value and equal or higher voltage rating. These old paper caps can have excessive leakage (DC resistance), intermittent opens, or shorts.
