I know.
Have you ever seen a Series II with the wood sides and the gun metal top? That is a hot enclosure. Speaking of hot.
Sorry Glen - I just can't help myself.
This looks complete now
I added some heat sinks to Q1 and Q2
Any one have preference for cleaning product to remove excess Soldering Rosin from Board?
90% Isopropyl alcohol.
D13L/R cannot be installed for a full comp application.

Here is the nearly completed mod for Series two
After narrowing the boards with a router on a router table I filed and sanded the edges to very fine finish .I looked for any copper trace jumping between layers before coating the edges with some 5 minute Epoxy. I double coated then to yield +/- 1/32 of coating.
The boards now have only about .005 -.010 clear
I then added a length of 1 mi Kapton tape to the frame ( anyone think I should double or triple thickness please let me know)
So now ready to put together
Thanks to Joe for all his tips and Eagle eyes (I missed omitting some Diodes) on this procedure I can now move forward.

I was going to use some sjoow 14/2 for the power cord and still may. I will have to rework that little bugger I guess.Look at where that AC inlet sits, right on the sheet metal fold, Geez. That is a big production no-no. The reins must have been very tight at PL during that period of time.

So we have the Backplates ready from wires now. I am of to my shop to change out the old 2n1303 cans.
I was a little confused about D2 but it appears it is not required any more. Am I correct?
