Cinematronics/rock ola armor attack pcb and condor cp573help.
hey guys,
im usually offering advice over in the monitor section but today I need some help from anyone that has worked on one of these cocktails.
so I have rebuilt the power supply, the condor cp573 fully and have all of my voltages. I have also rebuilt my monitor and I Have high voltage and the monitor seems to be working fully, its not breaking the switch fuses, or anything like that.
when I connect the audio pcb or the game pcb, my 5vdc rail drops to 2.04ish vdc. this caused me to go through the power supply again and again, but I have put in a new LM723, I have tried several different 2n6055, 4004's 3055's, etc and the same result the 5vdc rail loads down heavily when the sound board is connected.
Now, my actual ccpu is messed, when I test it outside of the game I get a solid lit red led. I will deal with that after, but when I connect it by it self. Now when i connect the ccpu to the power supply without the audio board, just by itself it loads the 5vdc rail right down to like 1.3vdc.
so I suppose my issue is with my power supply. at least in that respect.
has anyone encountered this? could the 8008 diodes be the issue? Or maybe the 1N5804's? the 8008s seem to the the ones rectifying the 5vdc all of my other voltages are accurate and correct. I have plus and minus 30vdc unloaded, and 6.3 is fine.
I repair electronics all day but this is stumping me here and I not sure I get it. Ive tried these tests with the monitor connected and disconnected same result.
when I do plug in the audio board and its only getting the loaded 2.04vdc its making the chopper sound sort of over and over.
the diodes are literally the only thing I have not replaced. I have some FR307 fast heavy duty rectifier diodes, I wonder if they will work in place of the 1n5804's?
I seen another thread where a fellow had this exact issue but there was no resolution posted.
I am going to be also for tips on repairing the ccpu once i fiqure this out!
thanks guys.
