Super nice pair of Threshold SA2 Class A mono amplifiers. These amplifiers are in great condition and sound beautiful. All literature original to the amps is included in the sale (including fuses and banana Plugs shipped with the amps (I will also include the amp stands). These are very sought after amplifiers that are built like tanks. Both amplifiers operate as they should at a temperature of about 47-50C. Both amps run within a degree of one another. 100w x 100w 8ohms or 200W x 200W 4ohms. I also have the matching Fet10/HL Preamp and Fet10/PC Phono Preamp (also in great condition) that I may also sell separately, or as a package for the right price. I will consider shipping to the buyer at carrier cost with insurance and signature.
