The assembly mounts to the soundboard over the pipe foot holes on a stamped steel base that has a valve seat formed into it. The mounting is with two small screws through ears that project from the round section of the base where the valve seat is formed. The rest of the base has a plastic (nylon ?) bearing for the armature and the pin that secures it and an extended section for mounting the coil. I have two chests that are full of these. Most have 3/4" valves and a few are 1 1/4". Coils on the smaller ones are nominally 90 ohms (except one that reads 120 ohms but functions OK).All I can find in parts catalogs is the Reisner 601 type that has a coil = parallel to the sound board. The chests were part of a Wicks organ, but I am pretty sure these chests were not original Wicks.   Anybody recognize these from my descriptively challenged prose ? Any ideas where I can get a few more of the 3/4" variety and the thin cork gaskets that go between them and the board ? Any help is appreciated. Maybe I should replace with the new Reisners ? There is room to do so.   Also, any tips on temporary repairs to regulator leather? The regulators have fairly good leather except for some small (under 2") cracks at the corner folds. I'd like to fix that temporarily to get started setting the pipework up for tests and wait to releather until I'm ready to mount the regulators in the final position.     Again,all help is appreciated.   Best Wishes to all,   Lloyd Collins lcollins@premiermeansbusiness.com

I don't think they've = made that particular magnet for awhile now, but I could be wrong at that. Frankly, I was not ever impressed much with that magnet design -- the metal valve seat/gasket arrangement is trouble prone with the passage of time, when the gasket dries out and compresses and they start to leak. (soft-cyphers for DAYS...<g>!) Reisners (and others) tend to be = more trouble-free once they're installed properly.   If your chests still work OK, there's not a particular reason to change them all out -- but I wouldn't worry much about trying to find matching ones for future usage.   >Also, any tips on temporary repairs to regulator leather?

Probably will work best if = you remove the reservior top and prop it up from within, while you apply the patches and allow the glue to dry. Be careful to keep the patches off = wood areas of the ribs, so they will all go away cleanly when you strip and releather the reserviors properly.     Good luck!   Tim Bovard Little Rock, AR

I repaired quite a few of them on a job once but = the fix worked OK. The plastic bearing on some of them had shrunk so that the =   armature became binding and I had to order smaller pins from Klann. If any = of them ever hang open, that may be the problem. Otherwise, they worked fine = and Klann was very helpful.   On another job once, a Moller made during War II, the plastic pitmans had warped and I had to replace ALL of them, insitu, using a vacuum cleaner to =   hold them in place until I could get the paper discs glued on. Don't ever want to do that again.   John A
