This legendary unit uses two vacuum tubes in combination with transistors.  See the close up pictures of the tubes in my unit in (1) power off, (2) pre-heating, and (3) power on mode.

Please see video link here for a virtual “demo.”  But I should mention that I was hesitant to show the video, because the sound captured by a smartphone does not do any justice to the actual, fantastic sound of this unit.  When I played back on my phone, there was buzz sounds at certain points, but again that is the limitation of the phone, not the amp.  I figured that it would be useful to post the video to show that this unit is working, but please keep the caveat mentioned above in mind when viewing the demo video.

In the video, you will see that I demo the source selectors including (1) moving magnetic phono; (2) moving coil phono; (3) CD; (4) tape; (5) tuner.

Before you bid, please consider the totality of the texts, images, and video as the full description of this unit.  If you have questions, please do not hesitate to ask.  I try my best to let you know all known issues or potential issues in this ad.  This unit is sold as-is and no return is accepted.  The unit’s cosmetic condition is great.  There are a few fairly light scuffs, as shown in the pictures.  A few times, one channel seemed to have taken 30 more seconds than the other channel to “warm up” after the unit was turned on, but I cannot always replicate this problem.  When I dialed the bass and treble knobs I could not tell whether I heard a big difference.  Could be my ears.  When I removed the front panel to clean the pots, I did see that the pots in the bass and treble knobs were turning as I turned the dials.      

The shipping & handling cost quoted is to the lower 48 states in the U.S. only.  If you are located outside of the lower 48 states, please consult with me before bidding so that we can figure out the shipping & handling cost.  I will try my best to wrap and package very carefully.
