Good afternoon once again,

I’m back from a weeks vacation and ready to start reworking the preamp. I completed my power test today. The problem I’m having is the fuse inside the IEC inlet is blown… Failed test. I put in my spare fuse and conducted the power test, I’m getting power through the cord into the back of the IEC inlet, Also 119 V to the fuse, no power to the transformer( Orange and pink wires) To the back plugged into the IEC inlet. No power to the B+….Took my spare fuse out and tested …….the spare fuse blew as well. I also tested the tube heater…… Tubes light up and I’m getting voltage to the tubes. I’m also getting very low ohm resistance from the RCA in side. Tested the diodes and resistors…… Those are testing Within specs.

Suggestions?

I could purchase new wires and try again?

My power transformer positive side barely has enough room to be connected to the IEC inlet…. Looks like I would need to extend those wires if I redo all the wiring.

Thoughts?
