Vintage Collins 51J4 Ham Shortwave tube type receiver Dead DOA Major repair Peter Dahl transformer

Full days repair of the classic Collins 51J-4 receiver. Owner informed me, the radio would blow the fuse immediately, even without turning on the power switch! I suspected the main transformer. After inspecting it, yes the component was toast. The only drop in replacement is the Peter Dahl PWDP13063 made by Hammond, Canada, special order at market price. Will set you back around $300 after shipping. It has the proper dimensions to fit the chassis cavity. Mounting holes/tabs, line right up as the original, so no drilling required. I installed a surplus military turret board underneath for the wiring to terminate on. I also found the main filter capacitor and 5V4 rectifier tube were bad.
