Well the CRT is pretty good, I had to resolder the pins to get a good connection but after the initial warmup it tests quite good.
It's a 17LP4 though, I was hoping for a more useful 17BP4. The main difference I think is the LP4 has a vertically flat face while the BP4 is spherical.
Variac-ed it and it just hums loudly.
I've managed to cut myself twice with it, first I pinched the back of my finger between the set and a license plate the store had hanging on the wall, luckily it was a newer aluminum plate that bent and gave a little so I only got a minor nick, if it had been steel I probably would have hit the bone.
While carrying it from the trunk of the car to the house I managed to grab hold of a busted tube in the back and sliced a nice sized cut in my thumb.  |
The chassis looks like the one in my 14" Emerson, so-called portable. It is a low B+ design, using only one rectifier. The set uses high value 150 volt electrolytics, because of the half wave rectification.
The 17LP4 is an electrostatically focused CRT, that is a lot rarer than the BP4 types.
