Thanks for the reply. That is where I've been looking, nothing that resembles a fuse or fuse holder in this tank cage that I see on the bottom.? There is a 3pos terminal strip mounted inside the back panel by the receive antenna jack with what looks like a diode/lamp on the bottom but one end goes to chassis ground so to me that isn't it.?? I do see what looks like a lamp but it's mounted outside the final cage near the transformer. The SO239 center goes directly to an inductor that is connected to the relay.? I need a picture...? I didn't buy this rig to work on it, I'm going to spend maybe another hour on this jewel then off to market she goes.... Looks great with rated power out.
