Full Restoration of my 1956 Heathkit AR3 receiver

 

The following pictures show various stages of the full restoration of my 1956 Heathkit AR3 four band short wave receiver. Full restoration consist of complete disassembling of the receiver, cleaning and painting the chassis, and reassembling of the receiver with all new components, wiring, and mounting hardware. Major components such as variable capacitors, dial, IF transformer, power transformer, etc, were cleaned and reused. The clear dial cover was replaced as the original cover was discolored and melted. The IF transformers were disassembled, the Mica capacitor material was removed, and the IF cans were reassembled. The cans were mounted to the chassis and 100pdf mica caps were connected across the primary and secondary winding’s at the appropriate assembly step. A fuse holder was added, Heathkit did not include a fuse holder in the original design, and the original power cable was replaced with a 2 wire polarized power cable. Rubber grommets were replaced when required. Testing was successful without any problems. The chassis and coil assembly bracket were painted Rustolium Metallic Copper paint.
