I have a palomar skipper base amplifier and the MRF 454's went out. So I did some looking around and found I could use the sd1446 as a replacement instead of spending $80 for the 454's. However unless I was tx into a dummy load the amp would oscillate and not unkey unless on low power. Now The 1446's have blown!!! and the output transformer gets really hot. Please help!!!
