TV Test/alignment gear on the cheap (and small)

[VintagePC]

Neat, but not particularly useful for my current 21mhz IF set.

is a variac. And maybe an isolation transformer.
Some variacs have isolation built-in.
There are times when you want to slowly bring up a set particularly if you don't know much about it or if it has been sitting awhile.

Then a VA62 with the EPROM mod is called for - the older tube alignment generators probably would work, but a VA62 can come cheap if it's local pickup. Around here, they have all migrated out of the area. I've not seen one locally on CL or eBay since 2010 or so - my eBay saved searches all yield >500mi away listings, and only Goodwill has had one close, but it was a basket case, missing knobs.
