Modification Photos for Part Number PWDP13026

Installation (Heathkit SB-220) Amplifier

 

Photos compliments of Dennis (N9AD) 2015 - WELL DONE:

The Heathkit SB-220 requires modifications to the perforated internal cover to handle the Heavy Duty version of the Peter W. Dahl - PWDP13026 transformer.

The cutout measures 2 3/4" x 4 7/8" (7 cm x 12.4 cm).

Dennis was really lucky to nab a N.O.S. (New Old Stock) - SB-220. He had the original chassis black powder painted before starting assembly. A few photos are shown below to help you with some installation ideas. WELL DONE!

Remember - these voltages are lethal and any repair and/or modifications should be made only by people experienced with high voltage circuitry & safety.
