The RCA 5R4GYB data sheet shows 20 μF. as the max. sized cap. allowed. So, that variant is definitely safe. IIRC, AA sponsor Jim McShane has some RCA 5R4GYBs.
The "potato masher" gets its moniker because it slightly resembles a WW2 German hand grenade. The actual types are 5R4WGA and 5R4WGB made by Chatham and Cetron. The variant was developed for use in (sic) B52 bomber avionics systems. :>D Oddly enough, the data sheets I looked at show 4 μF. for the "masher". However, I've never heard of the "masher" arcing into 20 uF., at the voltages we routinely work at. It's a very tough hombre.
