AMPEG SVT4PRO REPAIR
Pain in the ass repair from several months ago. This is the first time Ive worked on this model so Im sure the next one will go much faster. Resolder the bridge rectifier. Test all the 5w wirewound resistors for opens. Replace 10v Zeners. Check the bias circuit for updated design. This is probably the hardest of all the mosfet ampegs to repair IMO.
