Very thorough and informative! Thank you so much for taking the time, it’s greatly appreciated.

Okay, I reached out to the nice young woman that I purchased these from and and she was kind enough to give me a little more info. This is what she said.... "My Dad’s best friend Gary custom built that amp for my Dad when he worked at Phase Linear. I’ve been told the story and specifics a few...

Not at all! I work in the parts department at a Nissan and VW Dealership and geek out on car stuff all day. I dabble in photoshop and made this unimog jeep monstrosity a while back.

You guys rock! Thanks for all the insight and suggestions. I really appreciate it, so glad this place exists! I powered it on with a dim bulb, and all is good so we put it in the living room, fired up some Huey Lewis & The News and It’s totally a runner! I like the idea of keeping it as original...

Hi everyone, Sounds like this is the place to be! (lame pun) I am hoping to learn from and humbly participate with this extremely knowledgeable group. I am very new to vintage audio equipment and have a lot of questions! I recently acquired the following family heirlooms: Phase Linear 700b...
