I was thinking about using hot wax to mount replaced DC caps and hold new wiring in place during the repairs.
Is this a good idea, is there another solution to hold components and wires.
Would the tube radio get hot enough to melt the wax in time?

Why would you want to hold components in place. Aren't they attached with short leads to tube sockets etc?

Might consider epoxy if it's necessary to mount parts. Resistors and other radio components can get hot enough to melt wax. Wax melts at lower temp than tar. We sometimes find tar in a radio which has dripped from heat.

Assuming you are trying to prevent vibration from possibly moving larger components with long or reliatavely feeble leads, you could just use a high temperature silicone caulking material. Do let it cure thoroughly before applying powerm as some of these compounds are conductive when wet. I've seen this done hundreds of times on PC boards to anchor filter caps firmly. "A little dab will do you."

If this is the under the chassis multi-section type. dress the wire leads with insulation. Place the capacitors close together. Use clear RTV silicone adhesive to hold them to the chassis.

Warren,
These are under the chassis multi section types. I will take your advice and dress and use RTV silicone adhesive. I will transport the radios in my truck and then remove the chassis to insure that it worked. I am just a real careful engineer.
Thanks fo rthe solution.

Mitch, I sometimes use plastic ties to handle that job, that usually stabalizes them. You can find them at RadioShack.

:I am mainly concerned about the DC caps where the old large one is clamped with long wires connected to the tubes. The new caps are much smaller as you know. The new caps do vibrate when i transport the radio. I was afraid the cap leads might touch and short when the radio is put together and i can't see inside.

Working on airline avionics, I quite often found heavier components mounted to the PWB with RTV silicone rubber. I is impervious to everything but a razor blade, that insures easy removal of a defective part.

:Hi Mitch,
:
:I normally use spagatti tubing on the leads of capacitors and resistors. This will prevent leads from shorting to the chassis or other components. I have not yet found the need to use glue or silicon to hold caps in place.
