Hi all,
I scored a photomaster PM08 and a set of PM10 lights w/stands more or less for free. I managed to get it all powered up and it works just fine. One of the flash lamps is dead so I have a new one on order. I can hear the one unit try to fire so it is a lamp issue. Modeling lights work as do the hi/low outputs.

Only one big issue..once I fire it I need to turn it off to reset and fire a 2nd time. As soon as i turn it off i can fire again instantly. Whne I fire all lights stay the same but the "ready/test" does not light back up.

I have looked high and low and cant find any sort of diagram on how this guy works. I am more than willing to dig in and try to figure it out.

Any suggesstions?

Thanks!
