Hi, I'm an old tube jockey who is getting back into electronics in my retirement. I'm working mostly on guitar amps and old AM radios, but I have a lot of experience from my days in the shop -'72 to '82. It was a small shop, but we did a lot of shop work, service calls, antenna installation and CATV troubleshooting. We also had RCA sales and warranty - back from the days when companies actually valued their distributors. I got out of the business when it was clear that we were shifting to an economy of sustained disposal rather than repair. I also worked a couple of years prior to the TV shop at a regional electronics wholesaler - Hurley Electronics/Hemco CRT rebuilding, for you in the San Diego-LA area.
I still remember a lot of hands-on repair - I was an ace mechanical tuner refurbisher, but I couldn't align an IF for the life of me today. Those brain cells must have been recycled for my physics class (I went to college after TV, got a chemistry degree). I also did a lot of mechanical refurb on turntables & tape decks. I'm looking forward to perusing your posts and helping the folks carry on the trade with the scraps I have left! Maybe trade a few service call stories!!!

Cheers, James
