Hi all, don't know that this question went out on the list: Friday I was tuning up my T-4XC on 80M. Heard a very loud POP came from somewhere behind the front panel. No smell of smoke or oazone.
Never tune for more than 4 or 5 seconds at a time and never off-resonance more than 1 or 2 seconds. Before this incident, the xmtr tuned up to 120 to 140 watts (according to my TW-1 talking watt meter); after, it now peaks at about 80W. I had a QSO afterwords, so I know it's working some. Antenna match is about 1.3/1. Do you think I did something real bad or maybe it's just a tube or a plate choke or something? Where should I start to diagnose? Thanks, anybody. 73, Howard, WA9RYF
