My plan was to remove a few and reinstall them on a new chest I = had built for a flute, which I did. Here are a few things to watchout for:   The valves work okay, but have given me much more trouble than the wicks/reisner/peterson etc direct pallets I have. First of all, I should = have just used the old windchest with the valves already installed. The valve = seat sat on a cork gasket which did a good job of sealing between the valve = seat and the topboard.   When I reinstalled the valves into the new chest, the cork rings had dried = and stuck to the topboard, breaking up when i removed the valves. I had to = sand off all the old cork flakes, the seal was still okay (no ciphers) but not = nearly as good. Next time however I will purchase or try to purchase replacement = cork gaskets.   Also the armature is easy to bend off, causing clickiness and/or ciphers = during operation. And probably the most annoying part to me is the leads which = tend to snap off from the coil forcing me to resolder the lead from the coil.   Once these valves get installed and are fine-tuned they tend to work just = as well as the other makes I have. I can't speak about the long-term = operation since I have only had them installed for 6 months or so.   P.S. Do your valves have the Klann logo and part number written on the = coil wrapper? If they don't I can send along the part number if you are = requesting more information from Klann.     -Drew                 8/29/02 00:30:01, "Residence Organ List" <> wrote:   >DIYAPASON-L Digest #632 - Wednesday, August 28, 2002 > > Thanks for the help > by <> > Re: [Residence Organs] Thanks for the help > by <> > > >---------------------------------------------------------------------- > >Subject: Thanks for the help >From: <> >Date: Wed, 28 Aug 2002 17:35:30 -0500 > >Hi List Folk > >Thanks for the help and advice with those "different" direct electric >magnets.
