Philco 48-206

Nice job, Sam. I also absolutely love the meme "I'm not buying..." Hysterical!!

One suggestion, consider rewiring the power switch to the "Hot side" (Rectifier plate and rectifier filament string, and the neutral to the B- and 1st AF end of the filament string. and utilizing a polarized plug with the large pin to the aforementioned B- / 1stAF Filament point. Ever since there were transformerless sets, the mfgrs placed the switch on the B- / 1st AF filament point. on the earliest and some like my Emerson 330, there was no isolation cap, the power cord connected directly to the chassis through the switch. In this configuration, there is always a chance for the chassis tp be hot. Even if the plug was inserted so that the Chassis was at neutral potential with the switch on, when the switch is off, the chassis becomes hot through the filament string. When filaments are cold, there is much less resistance than when they are hot. this is why a tube in the string or the pilot light glow bright when the set is first turned on.Moving the switch to the Rectifier Plate / Rectifier end of the filament string and ensuring that B= / 1st AF tube filament is tied to the neutral wire on the power cord will make the radio safer. Hum may be slightly increased, but the shock hazard by coming into contact with the chassis, shafts if the knobs are missing, or the chassis mounting screws is greatly reduced..
