    Dynaco stereo 400 distorted channel repair

    Hello, left channel is distorted at any volume. Found the emitter resistors to be brittle and cracked. I have a mouser cart to be filled. Any other known 400 issues? For now I've ordered 2. New pc-28 boards but if I can fix with a few mouser parts, I'd save $170. Which I'd prefer. Thanks yall.

    Dynaco st-70 identification

    Just picked up this dynaco st-70 from a guy who got a bunch of dynaco stuff from an estate sale. It’s obviously a mk1 but it uses 6gh8a driver tubes. I’m sure the driver board has been replaced since it looks newer and definitely has new caps and resistors. Any info would be appreciated.

    Dynaco A25 XL, Restoration Process

    I recently got a hold of a pair of Dynaco A25, for $20cad at my local thrift store. After reviewing them online, I realized I got the XL version. H086 tweeter with SEAS drivers. They are pretty beat up and I have started restoring them, and will go up to refinishing the cabinets and rebuilding...

    Klipsch KG4 vs. JBL L26

    For the last three years I’ve been on the hunt for some Klipsch Heresys at a reasonable price point ($550 or below), and though I’ve come across a few possibilities, it has never panned out — someone always makes their way to the deal before I’m out of work or something like that. Pretty...

    Dynaco A-25 Restoration

    Hi all— This is my first time posting on the forum. I just bought a pair of used Dynaco A-25s at an auction. They sound great, but have light discoloration (pictured below) and are missing a grill cloth and frame. I found a great fabric match as well as the Dynaco name plates. This will be a...

    Klipsch Tangent 50 Value

    Hi everyone, I'm wondering what a decent price would be for Klipsch Tangent 50s in good condition. I've found some numbers online elsewhere, but most of those posts are from more than a decade ago, when vintage audio was generally cheaper. I'm looking at a pair for $250 and am wondering if...

    DYNACO ST-120 Restore to former glory

    Dynaco stereo120a Restoration I have had this unit for many years. The last time it was in service was about 15 years ago. As far as I can remember, it was working well. I did not test the unit before I began working because I was worried about causing damage by powering up before some...
