Thinking all is done except heat sinks does everything look ok? 12L1, 11L1, 16L, 12R1, 11R1, 16R.... those would be for original backplaines right?



Right Ray...

From the looks of the left overs, you did fine. Double check all your work.

The original wiring for the power caps has 2 eye terminals to connect them the top one go to the buss and the bottom eye terminals have 3 wires connected to them right now one wire goes to the rectifier then their is an eye terminal with 2 wires crimped in it one wire goes the fuse holders and looks like the other wire went to the stock backplanes... do I need this extra wire that went to the stock backplanes any more or do I eliminate this wire as it looks like the wopl boards get their power through the fused and unfused wires. So another words those bottom terminals on the caps should only have 2 wires going to them from the fuse holders and the rectifier right?

No, you can eliminate the one wire that went to the stock backwall, but there will be some UNFUSED wires coming from WO backplanes to each cap...

Hi Ray
There are 4 #10 solder terminals in the wire kit you purchased to clean all of that up properly

hmm I am seeing wires the go from 11L and 12L to the caps from the pl14 board right now I have the unfused wires on the back planes going to the fuse holder tips...

OK.. now back to our regularly scheduled program lol... so to recap the unfused wires going from backplanes to fuse tips is correct? and the only other 2 wires that go to the caps will be from the pl14 board right?

That was just a plug for White Oak bud....

That can be tedious. Helps to make sure the leads on the outputs are straight and plumb....

found a little trick only took me less than 5 min to put the other 3 in... put the screws in the transistor then carefully lower the transistor into the holes the screws help guide the pins to where they need to be and transistor almost just drops right into the sockets :)

Well far as I can tell Geri is ready for her first electrified sex session... just pulled my dim bulb tester down it only has 100w bulb will that be ok? And my variac is rated at 7.5 amp but it was made in the 50's and everything back then was underrated....
