-5 volt in Blast City and Super Neo 29

[-Ace-]

Can anyone suggest the best way to attain -5 volt in both of these cabinets? Neither of the harnesses have -5 on them, so I am assuming that the power supply doesn't output it? I have a number of pcb's that utilize -5 and sucks that I can't play those in these cabs .Thanks for any advice.

I use a jamma filter board outfitted with a negatron, in my Blast cabs.

Jnx might have a few left - this is rapid fire but also supports a negatron:

JNX Spitfire - JAMMA Rapid Fire Inline Adapter - End of Life

I may have a spare one or two of these:
NLA: JAMMA Passthough 5v Voltmeters

I put an extra 5V PSU in mine. Tied the positive to GND, and hey presto, negative 5V.

Way easier to just buy a passthrough with negatron though.

that's a clever way to do it. Negatron is probably a safer option for those that don't understand electricity though.

You could probably wire a negatron right into the harness rather than using an JAMMA passthrough.
