I looked around the internet and slim pickings for PSU images. There was the odd one with the same resistor missing but that's about it.

So basically everybody's power supply in the whole the world measures correctly other than mine then :lol: :roll:

One in 1 million all right... 1 being the chances of me actually getting something which functions correctly :lol: :roll:

... mine is the same as the one from DoG with R18 missing and with DFB1 and Nova Falcon plus ATI MACH32 VRAM card it has a voltage of exactly 5.00V. Q1 on the Powersupply has 60 Degree after 30 minutes operation what is fine ...

On my Falcon I have R18 + a recapped PSU and I read 5.00V.

On 3 DFBs with the release firmware I have the FPU working in one, sometimes, sometimes fails on a few ops in fputest. On the other two so far the FPU isn't working (bombs in fputest). I've not yet beeped them out or tried any mods.

Have you tried a slower oscillator say 40MHz ?
