My fault, total rookie mistake - swapping antenna from 2510 to my Kenwood and got jumpers crossed while in the heat of chasing dx. 100+ watts up the 2510's hot little butt (could have been MUCH worse in about 30 seconds). 2510 now not so happy anymore. I fried my final at a minimum. Tried my usual suppliers -Digikey and Mouser and no help. MRF477's seem unubtainium. MRF497's platinum plated. Is $40 - $50 bucks the going price? I'm not really looking for more power out - just trying to get it back going - but if there is a higher power mod I haven't seen that is comparable in price I'd go for it. Where do you tech's source the '477's or '497's and at what $$? Help! - Rumrunner out...
