    Mike LaFevre and the Peerless/Acrosound IP

    Several years ago, transformer guru Mike LaFevre passed away. If you didn't know, he was the owner of all of the intellectual property of Dynaco, Acrosound, and Peerless transformers and apparently knew the "secret sauce" on how to wind all of them (including some Western transformers like the...

    Does anyone have any info on this (Acrosound?) amplifier?

    I rolled the dice on this amplifier and the iron tests good. (Well, the bias transformer seems to have a shorted winding so it was only putting on -21v DC...) Radiomuseum has this listing: https://www.radiomuseum.org/r/acrosound_ultra_linear.html And that's all I can find. Was it a kit like...

    Another Acrosound UL120 out of its ashes

    Hi guys, Another Acrosound saved from oblivion The story I've got on this one is the owner was an old retired tech who liked to tinker with things. So I got the 3 transformers and the chassis as parts. The chassis has an external smaller chassis attached on the left side, I believe hosting...

    Acrosound Stereo 120 rebuild

    I remember it sounds all right when I briefly powered it on many years ago. But I did not turn it on for long. It seems like coupling caps or diodes are not originals. I suspect the previous owner did some minimum restoration. But I may be wrong. I plan to change all the electrolytic capacitors...

    Realistic 210 reborn (AKA Acrosound UL120)

    Hi guys, I wanted to share the work I've done on a true classic amplifier, the Realistic 210, also known as the Acrosound UL120, just rebranded by RadioShack. As far as I know, Acrosound did sell Radioshack UL120 amplifiers just before they tragically disappeared in 1959. Radioshack just...

    New Acrosound project

    Hi all, Mid 2019 I had an idea in mind, but never actually made it as a formal project. It was a simple idea: creating an Acrosound 20, the monobloc version of the famous 20-20, but not simply cloning it, but rather adding a new amplifier to the Acrosound family, 60 years later. I know...

    Noobie with a simple Transformer question

    Hi, Long-time listener. First time caller... I acquired a "Realistic Output Transformer manufactured for Radio Shack by Acrosound" at an estate sale recently. The label is red and white like Acrosound labels. It states "Type RS-310." I am assuming RS stands for "Radio Shack" and this...
