We repair Bedini amplifier products. The most common models being the 100/100, 150/150, and 200/200 series.
When these amplifiers quit there is usually a complete failure of all the transistors in one channel at once. As most of the transistors used in these units are discontinued, we have researched a  selection of equal or better subs for the original numbers including much heavier rated power output transistors. We also replace some bypass caps that tend to dry up.
Cost of repair is  usually $200.00 - 350.00 depending on model as both channels have to be rebuilt to match.

These are unique amplifiers and have the ability to control "difficult" speakers due to the topology of the output stage.
We have repaired many of these successfully,  despite the reputation of these being "touchy" amps.
It is important that these NEVER work into a shorted load, they will be damaged if this happens.
