[NJARC] Saturday's repair clinic for an AK 55C

[Louis]

I've partially disassembled my Atwater Kent 55C chassis. Two of the 
metal cans have tar in them, one doesn't look like it does, still trying 
to remove the top to the 4th one.

The tar seems brittle and breaks apart fairly easily. Will "we" need a 
heat gun to get all of the tar out? I can bring one Saturday but if 
there's anything I can do now to move things along, let me know.

I've read the metal cans are soldered to a base plate which is screwed 
into the chassis. Has anyone removed/worked on these cans before to get 
at the capacitors inside?

There are wire wound resistors under the chassis that I do not want to 
disturb so removing the cans w/o removing any wires seems to be the best 
way to repair the circuit, it's unsoldering the base plates that seems 
like it may require effort, any comment?

I picked up a NEC model RM-701B tape recorder. It's a tube model and 
kinda runs (needs a new belt) but has no audio. I'll bring it too in 
case someone has some input on repairing it. There is a schematic inside 
the cabinet. - Louis
