And the nice surprise is that once I changed the blown fuse, it works. I also has the 1.3GHz channel C. Only question is what am I going to do with my 7th counter?

Nice score - congrats.  And as to what to do with your seventh counter, well, keep the top surface of it clear so you'll have a spot to rest your eighth when you get it, and get back to ebuy!

Managed to get a full working HP 732A + HP 478 Thermistor mount. Price was very reasonable. Now I can meaningfully check a number of my instruments. Is there much info on change in HF response of these over time? Can I trust the efficiency plot on the mount?  I'll be using it mostly for applications below 1 GHz so it won't be that important.

Well, if you're willing to pony up about 1.5k or so you can get 478 thermistor mounts calibrated and repaired by Keysight. They are still in use as primary rf power standards (if you dig around, you will find Keysight sells a modern rf power meter that uses thermistor mounts). When I considered having mine calibrated, the nice gentleman said they have hoarded a supply of spare parts for them so they are still fixable....for a price.

Now the obvious thing is you need to add a 6632B to go with it  >:D
