I have an amp I built using radial caps in the power supply, and have a lead that appears to have fused open (It looks burnt and was arc'ing). I would have chalked it up to a broken lead, but have had this happen once before in another amp. I attached a schematic of where the fused lead was.
No fuses blew, and I'm wondering how this could have happened Everything else checks out (tubes), and the amp is working fine now, but I would really like to understand how this may have happened. I attached a schematic of the power supply and where the broken/fused lead was.
The only other bit of info that may be useful is that the caps are stuck down to the board using GE Silicone II, which is 100% silicone and contains no acetic acid (which I know can lead to to corrosion in enclosed spaces when not allowed to cure). I am paranoid the silicone had something to do with it, but I was under the impression it is not only not conductive in a wet or cured state, but also a good insulator as well
Thank you for any guidance!
