The PHILCO Phorum

Having never done this sort of thing before, I thought that I'd share my experience and choices. Since un-soldering and removing all of the wires to this box seemed tedious, I disconnected the box from the chassis and carefully separated the box from its bottom (the part that I didn't want to remove the wires from). This took a little coaxing and wiggling, but eventually I was able to reach in and snip all of the wires. After some cleaning and unsoldering the lugs, I had ten nice clean terminals. I did crack the strip slightly under the chassis. A longer, thinner wire cutter would have helped.



Stepping outside with my heat gun and various tools, I finally was able to pull out the caps. I was unable to quickly and easily soften up the guts, though. I think patience is key here.



Next I cut some pieces of plywood to make an L shaped inert for the box. I fastened 2- 5 lug terminal strips across from each other and numbered them to best fit all of the caps. Despite all of my careful work, I managed to forget a 2.0 mfd and one 1.0 should have been a .1. I hadn't soldered yet, so no problem. Then I put a wire to every terminal lug. I made them all the same length, but I could have sized each one. With longer terminal strips, the ground lug could have been shared by 2 lugs and I wouldn't have had so many connections on that one lug.



Then it was a matter of connecting each wire to the correct lug on the chassis strip.



There was plenty of room in the box for the wires, so as I lowered the box down, I had to push a few of them out of the way.



It slid down the rest of the way nicely and I reattached the screws. Talk about a Let's-see-what-happens moment........well, the hum is gone (mostly) and it works a lot better. Now for that neutralizing business.......great, something else for the first time.

Messy ain't it! Nice job!! For the extra hum adj the hum pot over by the power transformer for least hum.
