OK, thanks for the info, I just assumed the orange drops being a type of mylar cap was considered a fairly stable capacitor and that I didn't need to worry about replacing them, but I'm guessing that in the late 1960s they were still fairly new technology yet so they must not of perfected them yet hence the instability you spoke of.
Thankfully I didn't bolt the chassis down into the cabinet yet (because I feared there was still going to be some issues I was going to have to work out yet) so I'll just have to remove the chassis again and check the capacitors again (especially the orange drops) and replace the faulty ones.
