I've been an AK member for a couple of years along with several other forums, ARF and Vintage HiFi. Much more of a reader, but occasionally I am able to help. Used to repair radios-stereos-tvs in the 70's and 80's, then had a change of employment. Retired in late 2015 and came back to the "repair" business as a hobby. I like this hobby as it really does get you thinking, and I find it relaxing to take your time and work through the problems of working on both tube and solid state equipment. I wouldn't consider myself a "pro", but haven't found a set I haven't been able to fix. My worst repair was a friend that bought an old Philco frankenradio, a model 90 cabinet with a 71 chassis. When he purchased it, he didn't look in the back - it had no tubes!
