Gottlieb - connectors, connectors, connectors!

For single sided edge connectors, replacement contacts are:
08-52-0072 - larger wire 18-24AWG
08-50-0134 - smaller wire 22-26AWG

Enough overlap with 08-52-0072 that it can be used for larger and smaller wiring.

I thought Pascal was using fast TR5 1/10 amp fuses as seen here:

But your description says otherwise.
Just so we can see what fuse is there, can you include a good picture of the markings on the top of the fuse?

Pascal uses a novel method to generate the 60V - he steps the voltage up. Actually a really good idea.

HH uses more displays than typical system 80 games, he might have been a bit conservative in the fuse rating. Which regulator is he currently using? Possibly on that heat sink near the fuse. From there we can start to determine what max current is (based on more than just the regulator). Never want to go to max rating but would be nice to know what a safe range is.

By far the easiest thing to do - ask Pascal.
