Another Zeck amplifier sorted. Slightly smaller than the last one done the other week, this being A PTV2200. Still powerful and capable of waking you up in the morning. Good design and you can work on when in pieces, which makes life much easier. Getting a few of these in with problems within the protection circuit. Which, seems to work well as I don’t see these with blown up output stages. That’s great considering these poor things have to tolerate mindless reggaeton being pumped through them at full tilt. Now I offer a basic charge for full refurb, covering all parts causing known faults. New capacitors in the power supplies and other checks to make sure reliable operation.
