Condition: Tested and fully working. Fully serviced with new tubes and quiescent calibrated. In excellent condition with just a couple of minor scratches on the body at the rear side. Comes with installed NOS tubes and additional 2 matched pairs of 6C33c tubes as spare. We bought spare tubes. Because these are rare. Might the tubes need to be replaced after some years. You can still enjoy the tube sounds, with the same tubes made with matching numbers.
