Hello Karen, Do you have somebody that could take the schematic and "stuff" the compontents into the unloaded board? If not, I suggest buying an "after market" reversible board. Syndyne makes one that I would be happy to get for you. They are very straight forward to install and get working on just about any Rodgers console. Here is a link to the reversible board: http://www.syndyne.com/products/ls2rev.pdf Please let me know if I can be of further assistance.

There is a thumb piston for it which I assume is an on/off switch. Rodgers does not offer this anymore and suggested that I call a local Rodgers dealer to see if they could help.I probably will have to do this anyway.My husband was able to get the volume at a reasonable level, it is far from perfect and needs a professional's touch. If the zimbel. has a board, my husband could probably put it together, but installing it is another matter, with all the talk of keyers and the like. Regards and happy playing, Karen Karen C.

My 340 uses a non-standard board for the Post Horn. By non-standard I mean it's not the one shown in the service manual. On this organ they used a ROC2405A board. It has space for (and populated) 73 keyers. The "red Book" modification manual for my organ shows the parts layout as well as the populating lists but no schematic. If anyone has a schematic for the "keyer' on that board I would greatly appreciate a copy. All I need is one of the keyers, I really hate to sit down and draw it from the board. I have been told that it is the board used for the "Festival Trumpet" but I have no idea what organ(s) it was used in. Kindest regards Frank Evans
