I feel very fortunate to have been introduced by my 55-year-in-business local audio dealer to a group of audio society folks and a few good techs in my area.
The introductions came about over time and NOT introduced as business transactions. It was more about meeting good caring people first.
From there new doors opened, learning more about mods, upgrades, and huge collections of gear, tubes, more than I ever imagined possible. With a little patience, kindness, and respect these type of folks will share their knowledge and skills with you. Ultimately they will decide to choose you, or send you down the road if you're a prima donna.
