    Upgrades for a Thorens TD 126 MKIII? (vinyl newbie)

    Hi! I'll be picking up my first turntable this Saturday, the Thorens TD 126 MKIII. I have no idea what I'm doing, but it seems to me to be decent. I'm paying 400 for it, and have 2-300 more to spend on upgrades. A friend is giving me new a cartridge to use, so I won't need an upgrade there. My...

    Another AR-XA Upgrade Question

    Hello Audio Karma, I'm trying to fix an AR-XA that's having tonearm-related issues. There are 2 problems I'm working with. First, I don't have the original headshell and second, the plastic tip of the tonearm is damaged, so it couldn't hold the headship if I did. I'd love to hear...

    Pioneer PL-510A | Suggestions for Cartridge, Stylus, and/or Headshell

    Hi everyone! I recently picked up a Pioneer PL-510A from a pawn shop that came with a Technics headshell, Shure M97 cartridge, and Shure N97EJ stylus. It's running and sounding pretty good so far. I thought a new stylus would be a good next step before investing in records, so I emailed Shure...

    Upgrading Vintage Marantz 1030 Power Supply to Zener Transistor

    Hi, First time poster. I've started cleaning up and recapping a Marantz 1030 as a summer project. It's going well.

    PLUG-IN VS DIRECT SOLDER CONNECTIONS

    I picked up a B&K ST-1400/II power amp at a GW for $40. A score, in very good shape, 125W into 8 ohms, 165W into 4 ohms, good quality parts. Works fine, has a very good basic sound— but not great. I’d describe it as warm, musical, and “mushy” — smoothed off like a very old tube amp: lack of...
