Is there a problem with the -15 Unregulated supply? There is a 180 uF cap, C1113 that could be bad and let the voltage sag. Maybe that is the problem with your old A9 board. I could not find any reference to the part number of your old board. The -08 board is a later version and should work fine.
Check the -15 Unregulated level.
Regards

Subject: [TekScopes] Tek 2465 A9 HV module interchangeability ?
Hi there!
I have a 2465 with a bad A9 HV module--part# GB-7717-02.
I purchased another with a model# of 670-7277-08. This module was supposedly "removed from a working 2465" but seems to buckle the power-supply (i.e. the inverter loudly complains and all the front panel lights come on but never complete the power-on sequence). I was afraid to leave it on long enough to find out exactly which voltage is getting hammered but my intuition says the -15. The seller said it should be compatible...
Anyway, are these modules compatible and do you think I was sent a bad A9 module?
Thanks in Advance!
