[AMPS] SB-220 C4 failure

[W7OM@aol.com]

The 20 mfd electrolytic cap in the 120 vdc power supply ruptured.  This
failure occurred with a possible tube short.  Do not believe there is a
correlation.  Replacement is simple, BUT would like to know if anyone has had
a similar failure and is this is the effect of another failure.  I will
replace the rectifier diode too as it shorting would cause the cap to go.
 Diode passes the simple short/reverse resistance checks.

Thanks for comments in advance.
