Matchless/Magnum Meter Card 4091 replacement

Postby Gafro » Tue Jan 02, 2018 7:04 pm

Hello!

So it would appear that the meter cards on the magnum and matchless and interchangable. The magnum using the fabled UAA4091 chip and the matchless using the abundant LM3914N chips. Does anyone have a schematic for the Matchless meter cards? Would a daughter board containing the appropriate LM3914 chips be a suitable drop in replacement for the 4091 with some modification?

Any other information about the 4091 would be greatly appreciated. Pin outs etc.

Hello,

I have a Matchless and it doesn't have a 4091 or LM3914 on the meter boards. It is a discrete (rather power consuming) setup using LM339 comparators and an absolete LED display.

I have seen quite a few other Matchless console but never seen any other setup than mine.

I you really sure what you are looking for?
