Hey guys got a orion 8k here that had a blown power supply. Sucseed fixing that. But it's always had an issue with the relays sometimes on power up they would just go click click click. (Not fully engaged)
I removed 1 of the relays for testing. Ended up replacing the whole lot.
But now they won't switch at all. I assume I've gone in too hot with the iron while it still held rail volatge and I've popped something (nothing visable)
I replaced the PNP driver underneath the driver board just coz I had a spare. Didn't help.
They do engage if u bridge 2 pins on that driver but then they don't disengage.
So need to find out what's gone wrong.
I've checked over all traces.
Replaced PNP driver marked Q533
Replaced all relays
U can get them to engage by bridging 2 pins on Q533.
I've been over the power supply drive board components because this is how they are powered. All seems fine?
But getting old my eyes are not very good on these small components and numbers on the PS drive board.
Any ideas please?
Edit. All power supply and output FETS are switching as normal

I’m working on the same amp same issue .
Can you take pic of this area under the power supply driverboard ?
And measure the resistor R799 and tell
Me the value ?
I’m working on this one and I should have an answer to your problem as well

Orion hcca 5000.1DV2
I have a 5K Orion doing the same thing. Relays continually click after 5 to 10 relay clicks amp will finally turn on. After turn-on amp works great. After letting amp set for a while and all caps discharge amp turn on first try, but if amp has been recently powered up it will go into relay clicking. Any help would be greatly appreciated....thanks
