TUBE AMPLIFIER REPAIR

I have been repairing old and new tube amplifiers for the past 30 years. I have repaired many makes and models, including:

        Fisher 400C, X100-B, 510-ST, 30-A
        EICO HF-89
        Harmon Kardon (HK) A500
        Heathkit EA-3, W4AM, Stereo Amp
        Knight KN-330 (Tuner/amp)
        RCA MI-12224 (Early PA amplifier)
        Realistic 201
        Calrad

REPAIR VS RESTORATION

       I repair equipment and do not perform restoration.
       Restoration involves placing new parts within the shells of the old parts, or placing new parts inside of moulds of old parts that are painted to look like the old parts.
       Repair involves installing new parts under the chassis. All exposed parts on top of the chassis stay in place (are not removed).

DEFECTIVE COMPONENTS

       Defective components shall be replaced.

CAPACITORS

       All filter and paper capacitors shall be replaced.

TUBES

       All tubes will be tested for Emissions and Leakage (shorts). Bad tubes shall be replaced.
