eyah.. so now there’s a 514D in the house.  HELLO WINTER PROJECT!
This was a gift, and by far the oldest bit of Tektronix kit in the collection.  It’s a real beauty too.
This one needs the works – pull & check all tubes, thorough cleaning, check all caps, rebuild the fan motor, and replace about 8 – 10 missing tubes.  Some of it can happen in parallel, and there’ll be periodic posts.
