A little bit of Christmas fun (I'm not home). This radio was quite the trip. The usual bad filter capacitor of course. But someone also put in an ECC86 in place of an ECC85 for the RF amplifier section. The 86 is a battery powered tube, can tolerate at most 30V. The 85 here runs at 180V.
A bit ugly, but didn't have anything else on hand.
