Peavey’s TL604 Adapter Kit.
You will need soldering iron, solder and a bit of installation ingenuity (parts and instructions included).
The TL604 dual analog switch is obsolete and no longer available. Please note that this adapter kit will effectively replace the 604 and provide the same functions required in Peavey products. The only drawback, of course, is the size of the board versus the original part. This kit is supplied with headers and ribbon cables to provide two types of mounting schemes: the 4-pin headers will allow the board to be simply plugged into the existing TL604 socket if space in the particular application permits. The 4-conductor ribbons will allow the board to be “remote mounted” if the unit has limited access space. This type of mounting may require a bit of “rigging” to ensure the board will not short to adjacent circuitry.
