    Stereo Console Power Supply Issues

    Hi Everyone! I recently got a Magnavox stereo console to upgrade off of Facebook Marketplace. I checked it out in person, and the console turns on and can very poorly play AM/FM radio, which seemed like good signs of an excellent base to work off of. I took it to an audio shop to get checked...

    DIY partially 3D printed Linear Tracking Tonearm!

    First post on here, back story: Recently got a Sony PS-LX1 for cheap, which is a decent DD turntable, but the issue (and the reason why it's so cheap) is that the tone arm is broken. (somehow the metal tube is snap in half.) I've always wanted a linear tracker, but those are not cheap. And...

    Source for Dynaudio 17W75XL drivers?

    Does anyone know of a source for good used or NOS Dynaudio 17W75XL drivers? These were used in some Dynaudio models, many DIY kits of the 80s/90s/ and Totem Acoustic models such as the Mani-2. I have read that Dynaudio themselves won't sell any drivers directly to anyone anymore.

    In what order would you inspect/test/repair an old speaker?

    Someone in my neighborhood decided to give away their pair of Wharfedale W60D's and I decided I'm going to get into refurbishing vintage speakers. I did some research on them and it seems they have fragile tweeters - and indeed these have one broken tweeter - and can usually use a recap...

    VU meter problem BIC T-1 deck

    Even with the power off, the right needle stays on -7 db. With a tape playing, it's too high,usually over 0 db. The needle isn't stuck: I can move it back to the far left manually, but it returns to -7 when released. Repairable?
