1951 Kay 112 Deluxe Lap Steel Amp Repair and Demo WITH Tweed Fender 5C3/5D3/5E3 Circuit Discussion

This video covers the repair and analysis of a gorgeous Kay Deluxe 112 Lap Steel combo that was given to me by my mentor and friend, Hartley Peavey after he scored it at a flea market. It needed extensive repairs in order to be safe again. He knew that I wouldn't give up on it, and I glad that he was right! In the process of troubleshooting it, several cool and interesting anomalies were discussed, including the intricacies and similarities that exist between these types of amps and the ubiquitous Fender Tweed Deluxe 5C3, 5D3, and 5E3 models from the same era.

UPDATE....I had the tone controls figured all wrong. I got a schematic from Tom's Amps and quickly noticed that the Tone and Hi-fi options were actually in a feedback network. The HI-FI switch actually kicks in a RESONANCE feedback cap....not a Deluxe at all and in a very cool way! The phase inverter is NOT a long-tailed pair as noted, rather, this has a SELF-INVERTING power section using 2 x 6V6GTs in totem pole push-pull arrangement. What a cool little amp!
