Seeburg q160 TSU1 recapping

I decided to recap my TSU1 from my Seeburg Q160 which did not look
that hard. I have recapped old radios with success before. After
completing the unit, I tested it and one of the 0A2 tubes glowed
orange at the base. I turn if off in seconds. I rechecked my work
and everything looks good to me. I am by no means an electronics
expert. What are the chances of damaging anything by this? Any ideas
where I could of when wrong? Thanks

I'm not sure about the Q160 but the TSU from my 222 was positive
ground - which meant the caps had to be installed backwards. Could
the Q-160 be positive ground?

Yep, it is positive ground a REG -300V supply........GC

Verify that you have the POSITIVE lead of the two electrolytic capacitors
located under the chassis connected to the chassis. The TSU series used a
positive ground on the high voltage side. If you had these connected wrong
you'd more likely see internal arc-over of the 6X4 rectifier tube.

The 0A2 tubes are gas discharge voltage regulators which normally glow purple
once the 6X4 heats up enough to begin conducting the high voltage.
