§ Nixie tube clock $50 obo    posted Feb 9, 2026, runs thru Aug 9, 2026 (show)

  • A tinkerer's delight
    I bought this "homemade" nixie tube clock years ago
    but it is a bit of a pain to set.
    It has exposed wiring inside the lucite case so you need to know what you are doing.
    I believe genuine nixie tubes are a rarity so it may be usefule for the parts.

  • This Nucleus has an internal 1TB SSD and is in excellent condition. It comes with an auxiliary Switch Mode Power Supply filter as featured in the September 2025 issue of audioXpress magazine. Price is $1,100. I can bring it to a meeting or you can pick it up and listen to my new BACCH system while here.

§ British Fidelity Class A power amp and Preamp    posted Jan 25, 2026, runs thru Jul 25, 2027 (show)

  • Musical Fidelity Power Amp P270.

    The Musical Fidelity Power Amp P270 is biased at 100 watts class A per channel and will deliver 150 watts per channel at 8 Ohms (typically 200 watts) and 285 Ohms at 4 ohms. Bandwidth is 10Hz to 80kHZ (-3db). Each channel has its own independent power supply which are large toroidal transformers. Sounds Great and works perfectly except for the power switch/light which does not light up but does turn on and off the power. Asking $1200


    Musical Fidelity Preamp MVT Comes with a separate power supply and has inputs for MC/MM, Tape, Aux and CD. I have updated the op amps which improved the sound but cut out the MC. I have the original op amps if you want to switch them back. Asking $750


    Musical Fidelity’s founder was a professional musician named Antony Michaelson who, according to company literature, “dreamt of making an audio system that sounds like tube and Class A amps.” His vision was a product that was “warm and musical but [allows] the real-life dynamic reproduction of music, especially big orchestras.”


    If you buy both this amp and the matching preamp I will discount the combination. I can bring these units to one of our meetings.

§ 8 Vicoustic Multifuser DC3 Diffusion Panels (two sets of 4) Slightly Used - $450 for all 8    posted Dec 27, 2025, runs thru Jun 27, 2026 (show)

  • Vicoustic Multifuser DC3 Diffusion Wall & Ceiling Acoustic Panels - 4 Pack at AudioAdvice
  •  
  • I have purchased these panels on USAudioMart for $600 ( $100 for shipping). Listed price is $450 for a set of 4 (see the AudioAdvice link). I am ready to sell all 8 for this amount (50% off).

    4 of the panels were new, and 4 were very slightly used. I have tried them in my two rooms and have not seen/heard any noticeable effect. I haven't actually used them at all, but drilled tiny holes in the backsides of 4 panels to hang them using removable wall brackets (purchased separately) during my experiments. You can see these holes in the photos. I can conservatively rate the panels' condition as 8 or 9 out of 10.

    You can see more photos here: https://1drv.ms/f/c/f8fc4a21320773ea/IgAxraVaelvRTazxDrO8-YlFAWWZk3F-d0wkUEPH9aLyyQg?e=H6FRtz

    Somebody's loss is another person's win, so you can have all of the panels for $450.
    The panels are packed in two big but very light boxes (4 panels each).
