Hello everyone!

I've got a neat old speaker that needs attention, a University TMS-2 "stereo-in-one-cabinet" 1950s' number, rearfiring 12" dual VC woofer handling 150 hz & down, two 8" mids and horn tweets firing out of each side. I love this, it really rocks, which as I age includes the ability to do justice to jazz & orchestral pieces .

The problem I'm having. At lower levels on side is quieter than the other. I've tested all the drivers and they appear to be fine.

Each channel has L-pads for the mids & tweets, and are my first suspect. I have tried cleaning them but the "second layer" of the pad has no holes in it!!

How do I find out what values they have, I think I need resistance in ohms? so I can replace them.

Also, the crossover components are waxy paper cylinders that I have heard go bad, and are possibly a upgrade target anyway.

The components:

To tweeter: 1" dia. x 2" long cylinder, marked 85_LPT, MFD_V.D.C., 2._50, USA _[pyramid symbol]472

To mid: 1" dia. x 4-1/16" long cylinder, marked MallorY, 150_MFD_V.N.P., 44A155B, 235913X.

To woof: 1-5/8" h x 2" w thing, looks to me like an inexpensive transformer, marked 72B114B, MEC.

I'm thinking these are great candidates for a complete electrical renovation. I've already drawn out the circuit (if that's what you'all call it!).

Any advice/suggestions are appreciated, I'm a newbie to DIY crossover work!!

Pete
