This is my first time restoring a capacitor tar block on a radio. This is the metal box with 5 film capacitors, not the bakelite block. I've got it apart and plan on reusing the original wires that come out. I don't have circuit board material on hand, but I'm planning on cobbling up some cardboard and perforate holes to secure the capacitors. What I'd like to know is what different concepts people used to secure the new capacitors in the metal box, maybe better ideas than what I have in mind. The radio is a Philco Model 60.
I don't remember any tar block caps in 60.
There is a gang cap can with 5 caps but it is not a tar block. Caps are tared tobether but not to the can.
You simply open the tabs, take the cardboard front off and pull the envelope of the tarred caps wrapped in fish paper out.
I simply solder the caps together at the GND, wire the leads, abd then pot the leads with hot glue after threading them through the cardboard front's holes if existing. The fishpaper serves as the insulator from the can.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
Here's a couple pictures of my restuff of the box for a 60MB. I didn't take as many photos as I should to show what I did. I did not reuse the original wires and simply bundled the film caps together with some electrical tape after soldering the ground side of all caps together and running a wire up the side to be soldered to the side of the box. A little heat shrink covered any exposed wires on the positive side of each cap and then all leads went out through the original black fiberboard cover and the box tabs were folded down to make it all snug. The cardboard lining gave enough for the black fiberboard to seat onto.
When I rebuild a can like that, I reuse the original front and back insulators, the original fish paper, original lead wires if they do not have damaged insulation, and I twist the common leads together and solder with the original bare wire that is soldered to the can. Sometimes I inject some hot glue to hold the capacitors together but some electrical tape would do just as well.
Almost exactly the way I do it. I make point of reusing the fishpaper and front/back.
I mostly use the GND lead wire.
I do not always re-use the connecting wires as sometimes they are tarred too much.
