Subject: CRT Testing
I would never have thought of acquiring this set, but a friend (I’ll call him Philo) rescued it from someone who was putting it out with the garbage. He plugged it in and the screen lit up, so he shipped it to me. For free, I’ll try to put the set in working order. Philo will get a kick out of that.
I’ve pulled the chassis, and all the parts are there. The only shipping damage is one broken tube and a broken escutcheon, both easily repaired or replaced. And the yoke is loose on the CRT neck.
My next step will be to check continuities to ensure other significant components aren’t dead. I’ve tested the tubes, including the CRT.
I’d like an experienced person to assess my test results on the 17AVP4. With a Beltron 8080A, 6.3 heater volts:
No shorts.
Ten seconds to reach 0.45mA.
After four minutes, it reaches 0.55mA or maybe 0.65mA.
Interrupt: Current immediately decreases, reaching almost zero in seven seconds.
So, before I spend any time on this set, what can I expect from the CRT?
Thanks all,
Henry
