  • Vintage DYNA MODEL PAS Tube Stereo Preamp Stereophonic Preamplifier DYNACO ASIS

    I dont have a way to fully test this unit and im not even sure how it suppose to work correctly. The way I tested it is I connected a small sony speaker to the output plug and connected my smartphone to input, the sound is very quiet since as far as I know it needs an amplifier for the sound to be loud, but the sound is very disturbed, not clean at all, not sure why.

  • 6SN7 Line Stage Stereo Tube Preamp

    Built many of these since the Vaccum Tube Valley printed the plans but this one is a little cooler. Built as you can see on Dynaco 120 chassi that is in fair shape. It is like driving a sleeper hot rod, looks so so from the outside but?.

    Marantz 3200 preamp. Works perfectly. All bulbs are good and all pots/sliders/switches are smooth and no static. Used to push Bozak Concert Grands and the system sounds excellent. Power amp not available because I have been pushing the system with a Onkyo power amp.

  • MAGNECORD PT6-S5J RECORDING PREAMPLIFIER AMPLIFIER

    Magnecord PT6-S5J / RCA 74B Ribbon Mic - YouTube. It can be used as a microphone preamplifier, or an amplifier. It has a pair of 5881 output tubes and also used a Triad input transformer. It is working and sounds good as is but it looks like some of the capacitors have been replaced but not all, so it may need a filter cap or two.
