Welcome, kcvet, glad you chose to land here and stick around. You got into the biz as I was stepping out as a Sony warranty repair site in the mid-Atlantic area back in the 70s. Went into computers instead.....
I can assure you that your knowledge will be tapped from the folks who are discovering how nice the older Sony gear was.
The only problem is that when they refer to vintage gear, they're actually referring to us, too!
Again, welcome!
Cheers,
David
