I was mostly blaming the mains for that fuse. As the local area developed more houses ware added to the already long line to the transformer substation, additionally heat pumps became a popular way of heating homes here and that put a heavy load on the grid here. As a result i would get fairly low voltage in the mains of around 210 to 220V, this caused the HP 8566B brown out and reboot on a few occasions as it was set for 240V. To fix that i changed the mains selector to 220V and it was fine. In the mean time dad had a solar array installed and things got even worse, to the point where the solar inverter was throwing errors. So i set up a DMM to log the mains voltage over a few days and was shocked to find out it would at times dip to 180V while other times rise to 245V. I shown the graph to the power company and they hooked up there own voltage logger to indeed find the voltage is way out of spec. After some back and forth they finally ran a dedicated new line from the transformer station for this area. And that made the voltage rock solid.

Same issue.  New neighborhood, aluminum wire, poor connections, and the legs were out of balance.  One leg around 70 and the other 110.  When the neighbors would flip on their oven, my lights would dim. They ultimately pulled all new wire in my neighborhood which fixed it all.

By the way, many of the cylindrical silver caps are not electrolytic but tantalum, expensive little devices.  I picked up a couple of thousand of various values from a guy who repaired Tek and HP scopes.  Let me know if you need any by PM.

Smokey:
cool.

Loads of fun, especially for low band dxing. As an aside, the LO has exceptionally good phase noise performance, and I use mine as an RF signal generator below 32Mhz, with a step attenuator it really is useful on the bench.

Should you decide that the OCXO in you spare is surplus to your needs let me know, I've been looking for one half heartedly for a while.

I just remember them being polarized capacitors. While i was in there i randomly measured a few in circuit and they seamed fine. Some have said they are unreliable and start to fail horribly with age. But there are so many of them in there that i don't really want to recap the whole thing unless they do start to go bad.

Do you need to replace these with genuine parts? Wouldn't a modern electrolytic do just fine?
