I've had several problems with the 32xbr chassis, and the P4 module, its alomost always been IC1204. Phil

Since you are looking for a P4 board, you must have a problem with the Comb Filter. I may be having a problem with the same board. Someone suggested I replace all the Elec Caps. There were only 16, but the problem still persists. I hope we can help each other. What are your symptoms? - John
