Hey Guys hoping for a few suggestions on where and how to sell. Specific forum, expert, or eBay? My dad built this kit in the 60’s . Dyna stereo preamplifier, dyna FM tuner, and dynakit stereo 70. He used it up until 1989. I am not sure if it works or not. A few years ago I talked to a rebuilder who suggested I don’t plug it in. ( needs to be warmed up?). Any suggestions would be appreciated as I want someone to enjoy it.
