What you showed us regarding the power cord - Wow! Great job of sleuthing there Mr.Terry! Mental note made! Isolate the suspect part for testing! 😎👍 Cheers - Luther
Thank you for detailing your trouble-shooting method, very informative. My only complaint is the owner's mod of a blue LED indicator lamp, it should be AMBER : )
I think I have Snozzeramus' great grandpappy, a big old brute that MY grandpop used to used for certain plumbing jobs. Used to melt that thick old plumbing solder faster than a 40 watt flat tip on 0.020 Kester. One of these days I'll drag it out and make sure the old cloth covered wire is intact.
Hi Terry, I've actually experienced a defective power cord twice. Similar situation. Look closely at the conductors. strip one of the ends and take notice to see if you see any green, liquid oxidation. There were power cords made in the 60's that had this issue and would corrode the copper and cause resistance. I had a few Fender guitar amplifiers also that had this power cord issue. Great video.
Terry, Just a thought about the new power cord. Are the wires that make up the power cord rated for the total current that might be drawn for the amp AND everything else that might be plugged into the sockets in the back? I understand about the reason to not use a 3 wire cord on the replacement cord, but is there a reason that you chose to not use a polarized plug?
Why not use a polarized line cord as a replacement cord? It guarantees that you will be switching the hot side of the line every time.

I own a Dyna PAS 2 preamp that had the same problem except I had an intermittent no power problem. I replaced the cord and plug and the problem went away.

Terry,
Just a thought about the new power cord.
Are the wires that make up the power cord rated for the total current that might be drawn for the amp AND everything else that might be plugged into the sockets in the back?
I understand about the reason to not use a 3 wire cord on the replacement cord, but is there a reason that you chose to not use a polarized plug?
Indeed.. I was going to ask the same question. I would've thought a polarized 2 prong with the hot running to the new fuse location.
I agree that a polarized cord would still be a good idea. Keeping the hot line going to the fuse and switch. Only a safety thing.
!!! Another great video

some of the pass needs a mains fuse
always double-check
