Johnson used excellent transformers, capacitors, resistors, and a well-regulated, high-energy, power supply... In an elegant circuit design. The result of his staunch efforts.... Mids and Highs are Magnificent, and Bass is quite Respectable.... (also, If you are so inclined, and enjoy modifying your own audio equipment, there is plenty of chassis space for circuit updates).
However, tube audio equipment is very heavy each amp is 45 lbs. This equipment will be wrapped in, and with, ample packing material, however, I cannot guarantee the amplifiers will arrive undamaged... That is out of my control.
