is d530 ok?
D530 meters bad in circuit, I get about .400 one way and 2.400 the other way between the same two legs. Assuming I need to test it out of circuit, I'll try to take it out when I get home from the gym. There are huge solder blobs on the parts side though so it looks like it will be tough to remove.

I'd have to replace the HOT as well for this, right? Isn't there an easier way to test the PSU, can't I meter it while disconnected from the chassis to see if the correct voltage is being output? The reason I'm hesitant is that while I have 2-3 more replacement HOTs available, I'm out of replacement VRs and I really don't want to blow another one until I am reasonably confident I have found and fixed the short.
Would putting the light bulb in place of the fuse add enough resistance to protect the HOT / VR from blowing again? By my quick mental math, a 120 volt 60 watt bulb would add 240 ohms of reistance, right? Those run on AC, right, and isn't fuse 902 94v DC?
