It is time to replace the fans in my TS850S and PS-53, as they have become increasingly noisy. Apparently the fans needed are no longer available. For the transceiver: Panaflo OL06BO-1, model FBK-08A12H. For the power supply: PANASONIC OF13BO-1 Model FBK-08A12H. Can anyone help? Vy 73 de OZ8CTH / Peter
