Does anyone know if these two HVPS's are interchangeable?


10-310-01P model X2294

10-310-02P model X2532


The 02P looks a lot newer and cleaner and does not use those 6 2w carbon comp 560 ohm resistors that wander around in value. It looks like they're wirewound. I don't know for sure but it could have come out of a 1999 vintage 8500.


Specs and manufacturer are the same, so I really don't anticipate any surprises, just wondering if anyone knows for sure.

Bill,


Yes they are definitely interchangeable...


I had a 10-310-02P model X2532 coming from a 1999 9500 ultra.

The HVPS failed and I replaced it by a 10-310-01P model X2294 from a 8110. It works.

The 02P is definitely newer.


BTW, It's very weird because my -02P HVPS had the same 6 2w carbon comp 560 ohm resistors. I know because I changed them.

That's great, thanks.


This -02P has a very new looking pc board inside with a different layout and components than others I've seen -- that's what prompted the question.


In it goes...

Bill,


Tell us if you see any difference picture wise.

Thanks.

I have changed the 6 resistors in the 01P and couldn't see any difference so far with the 02P I had (but I only played with it for a short time).

Stef,

Were your 560k's off value or was that preventative? Those are 3 sets of 2 560k's in series, and each set feeds a G2 voltage for red, green and blue respectively. If they were off (usually high) it would require you to adjust G2 higher for proper black level, but that's about it. If they were wandering thermally, then your grayscale would be shifting around.


I don't like to see carbon comps in anything just for basic principle!


Yeah, I'll feedback if I notice any changes.

Bill,

Just preventive I guess but the PCB was a bit dark/burnt. These G2 resistors seem to get very hot.

My G2 adjutment was in the norm before I changed them and I didn't see any big difference after (but I played with it only half an hour).

Fascinating discussion. I'll never need a sleeping pill again! Just call up this thread from the archives and . . . .

Mark,


I hear you snoring...
