Antique Sound Labs Wave-8 8W monoblocks, fine for efficient speakers and pretty good with AKG K1000 phones too. I've almost finished my 300B monoblocks so these go to make room. There are THREE amplifiers - that's two to use and one spare, ideal if you want to tweak the circuit. This is the model with detachable power cord and tube cover, selling for $110 each. One does not work - It used to but stopped during my move from CA to NY, cause unknown. Telam ECL82 tubes are fitted to the working pair, a nice upgrade from the "Ei Yugoslavia" that were supplied. One pair of Sovteks included too. Other than the fact that one of the trio does not work they are unmarked.
