I'm not familiar with the light bulb that illuminates the meter but I'm assuming it's the older type of bulb that were used in flashlights. Definitely not an LED type. It's been blinking off then back on and ocastionaly dims without going out (weather I'm transmitting or not). Then there's times it won't dim or blink for the whole time I'm using the amp (45 minutes.) But for the most part it blinks 80% of the time it's on. Does anyone know if this bulb is secured in a socket or soldered in? The bulb itself has been dim as long as I could remember. Should I replace it or just wait until it stops working all together? Before anyone gets perturbed and says "why don't you just remove the cover and see for yourself". Being disabled is a bitch sometimes. Having to reply on other's is a part of my life I'm used to but having to ask my wife or someone else to do something that's not nessesry is something I avoid. Thanks. 73
