Sherwood AM-8500B Power Amplifier ?

Monster dual monoblock poweramp. 260W P/CH rms. Great condition, boxed / manual. Great sounding poweramp, i used this with a pair of TDL Studio 1 transmission line speakers. It uses 2 separate mains transformers and supplies, its a pretty heavy beast! Has gold plated connectors through out. Has 2 sets of binding posts which are enabled via 2 push switches on the front panel.
