Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

Classic and well loved tube amplifier which was produced from the 50's all the way to the 90s. 

Featuring a no nonsense design capable of 35 watts per channel which was refined to near perfection over its lifespan. 

This unit appears to be from the last years of production and is working perfectly.  It was tested in our lab under full load and the results were spot on.  

Cosmetically it's in real nice condition with no signs of abuse or rust.  The chrome is free from any pitting or deep scratches, and the paint on the cover looks great.
