Update on Model 87 restoration
#1

First, I want to thank you guys for the help and information that you have given me. I wanted to give you an update on my progress on restoring my Model 87.

I took your advice and decided to mount the capacitors in the can. I removed the can and used a butane torch to melt and remove the tar. I was careful not to get the flame too close and distort the can. It took forever for enough of the tar to melt and drip out enough for me to remove everything from the can. I cleaned the inside of the can with tar remover and alcohol until I got it completely clean.

Rather than strapping the wad of new caps together, I cut a piece of 1/4 inch plywood to lay them out on, sort of like a circuit board. I cut a piece of sheet metal to use as a terminal strip and screwed it down to the board, and soldered each cap's negative end to the strip, as well a wire to route to the chassis ground. The plywood fits perfectly into the can, and I put a thick piece of foam into the can to fill the space so that the board won't move around. I have reattached to can to the chassis and rewired all 10 of the leads. Double and triple checked correct wiring and solder joints.

I have ordered replacements for the 3 tubes that were missing (2 45s and an 80), so that's where I am now. If all goes well, I'll be listening to this thing in a couple of weeks.

Again, thanks for all of you advice and help.

Wendell
