Re: Tempest K6100 - intermittent HV problem

Ok, thanks again guys.  This is helpful and I'm beginning to understand a bit more about this.  You are dealing with a relative novice here.  Ok, I've looked up the HV over voltage protection adjustment procedures and...well....I don't have an HV Trim pot on mine.  Nor do I see an LED.  So, does this mean that I have an older version that does not have over voltage protection?  I read that this was a feature of the later version monitors.

I'm not sure where to check for the +13 that you mentioned.  I will see if I can figure that out unless someone hear can tell me off the top of your head where to check that.  And also I'm not sure where to check to see if the oscillator is running.  I have a logic probe and know kinda how to use it.  A little..... :)  

Any pointers would be greatly appreciated!  This is my favorite game!

John,   The install manual details the HV shutdown adjustment and how to determine if it's applicable (not hard to tell, once you see the difference).   It also explains why you shouldn't depend on the B+ to adjust the anode voltage.

The times when it doesn't work, the voltage just comes on way low and stays there (24 volts or something like that).  So it doesn't really sound like over-voltage protection to me. But that's an interesting fact to tuck away for future reference!

You may be running borderline on the HV. I believe the K6100 has an

high.

Did you adjust the high voltage after the rebuild ?
