I had an all SS Sylvania a couple of years newer than yours that your chassis picture reminds me of. After some years the tripler tended to arc over but I scraped off the carbon and siliconed up the sharp arcing-prone points on it and it ran for a number of years. I eventually replaced the tripler but an ongoing problem was the two heat sinked transistors seen just to the left of the HV section. They plug into sockets and the connection was sometimes iffy as they draw some current. One of them, the one on the right in the picture, would blow after a few months. Too much heat. I ended up sort of "corrugating" the transistor leads like a bobby pin so they'd make better contact, and putting plenty of heat sink compound on the transistor cases. I also made up and screwed on some aluminum cooling fins to the heat sinks. After that I had little trouble with those parts.
