Built the AR-3 shortwave receiver also, my second Heathkit, a basic 4 receiving tube radio at $29.95 and also ordered their fairly attractive assembled wood, cloth covered, case ($4.95). Cost was a consideration as comparable manufactured 4 tube shortwave sets cost $49.95 and a potential shock hazard as they were AC/DC radios instead of the transformer powered AR-3's.
Thanking everyone for their Service.
