Hello! I am wondering if there is any reputable people out there that would be willing to repair two Sansui SM-1500. The boards are in excellent condition, but a few of the Mosfets have become loose and need to be resoldered. The boards are exactly the same as the PPI 2075AM amps made back in the early 90's. If you, or someone you know, is capable of helping me out, please send me a PM or reply back. Thanks so much!
