\"Type LK-30 Laboratory Stereo Amplifier Kit\". Not sure of the date on this, but guessing late 50s or early 60s. I used this myself in the 1980s for a time, then stored it until a couple of years ago, when I had a techie check it out. He put four new ECL86 (expensive) tubes in it, and then I used it briefly, before switching to a more modern amp. This amp sounds fantastic! In addition to the above tubes it has 3 AX7s for pre-amplification and 5 AR4 tubes (not sure what they do). Some of the lettering on the face of the amp has worn off, and it is a bit dusty from recent storage, but overall decent cosmetic shape. It is sold as working, so if it doesn\'t you are welcome to return it.
