Adhesive for large electrolytic caps

Post by MikeC »

Just wondering what product the amp techs are using to adhere large electrolytic capacitors together to damp vibration? It's usually white rubbery (silicone?) flexible stuff!

Ordinary silicone sealant is good, the clear stuff looks a bit tidier.
Tube amp and guitar tones straight from 1958… amazing how believable the sounds were back then, even without the modellers...

Ta, I was reading that it contains substances that are corrosive (to copper tracks etc) - there is an "electrical" silicon but I can't find any! Cheers.

I use f2. If using silicon, you'd want neutral cure. The regular stuff gives off acetic acid, contributing to corrosion.

(Edit, didn't read JBs advice above before posting. He's right)

I have a tube of ADOS RTV Neutral Cure Silicone, but it looks like its gone hard in the tube now, its so old.

Thanks, I'll see if I can get it somewhere... Found it at Repco but still open to any other recommendations!
