I’m troubleshooting a DS that scans twice no pickup after making a selection. One of the OA2’s does not light. I replaced with known good OA2 still no light. Am I looking at a transformer issue?
Regards Rick
Rick....
Others may know better than me. But.... Has the pulse amp been rebuilt? I think there's a cap or resistor that is troublesome. Or possibly an issue in the pricing unit. I had a U100 that had a contact issue in the credit unit. Once fixed...made every selection.

Its been fifty years since I worked on one of those but there's high ohm value resistors that tend to open up causing this kind of problem. So, yes, the pulse amp needs rebuilding. On Tuesday, June 27, 2023 at 06:54:34 PM CDT, Rich Myers via Jukebox-list jukebox-list@lists.netlojix.com wrote:

Because the OA2 isn’t lighting I’m leaning towards a voltage issue. It didn’t pickup loading the tormat with a D cell

Do you have the manual with schematics? I would first look around the 0A2 that doesn't light for a bad resistor. If no manual/schematics, get some. They may seem expensive, but the time you will save will pay for them.

If these are original gas 0A2—not the Zener-in-a-tube, they must both be lit purple.
If only one is lit but there is normal voltage from the 6X4, you will have excessive write-in voltage. This causes all of a number and all of a letter to be written.
If neither are lit look for defective 6X4 or open resistor between the two filters.

ALL the electronics MUST be rebuilt or you will soon have a much bigger set of problems.

Did you happen to swap the two 0A2's to see if the problem followed the tube, or if the other tube now glows purple?

As I understand this, one tube is lighting and one is not. And it seems to me that "no change" could be taken to mean either the same tube stayed unlit, or the same position stayed unlit. I think that's the reason for trying again, for clearer communication!

Sounds like you don't have the over 300VDC power that is needed. The OA2s each light up when they regulate at 150VDC, if only one OA2 lights up, then the B+ is less than 300VDC so you have to solve that. Start with the B+ filter caps and the 6X4 tube.
