Hallicrafters S-76 post war shortwave receiver. Just finished repairing this relic. 2 days work. All caps were waxy drippers. Had to troubleshoot the IF amplifiers. That was pretty involved. Have shot a 23 min video of the repair. Will be posting on YT after editing. Thought you guys would like to see this piece. It is very rare, made in 1952. Cost then was $169! | D-Lab Electronics
