Here's where I am. I have an older Asteroids cab that is:
-New to me
-Plays blind, full sound, and graphics display on oscilloscope.
-I've pulled and checked the G05 boards & installed Bob's cap & transistor kit.
-C100/101 tested out good on the ESR meter.
-New Big Blue
-No neck glow
-No spotkiller
-Chatter from the tube
Voltages on the AR board are good. 5 is spot on, 10.3 is 11. something.
Voltages on the fuse block are:
1 = 5.73 VAC
2 /3 = 18.70 VAC
4/5 = 10.33 VAC
Voltages at the regulator board on P101:
1/2 = 26.73 VDC
3/4 = GND
5 = -26.35 VDC
6 = ----------
7/8 = 7.09 VAC
Before replacing caps & transistors, I had some on screen display, but it was totally garbled, vectors flying all over.
I'm looking for some guidance on where to go, what to test from here.
