    Default IRS2092, IRFI4019 ClassD Stereo Power Amplifiers

    For sale two ClassD Stereo Power Amplifiers

    I built these to evaluate the IRS2092 chip set, they ended up replacing my Quad 405-2 mono blocks.

    2 X 200w per channel IRS2092 CLASS D Stereo Power Amplifiers.
    200va Toroidal Transformers with 35v secondaries
    35amp 400v Bridge rectifiers
    4 X 10,000uf 63v Capacitance fitted in each amps power supply.
    Good recycled solid cases which may require nice fronts fitting if you feel the need.

    £80 each or £150 the pair

    Yes ok

    These amps are a real upgrade over those Tripath TA2022 90 watters which weren't bad.

    If either of these fall through, or they just don't suit the buyers systems, I'd like to step in for 1 please.

    Hi Mike

    As it so happens I do have another one of these.
    Built into a Gemini X1 pro audio case with a huge 500va transformer.

    I can let you have that for the same deal.

    Happy Days
