Worth of a Panor Dynaco stereo 80 tube power amp?

Hardly any info. on the worth of this amp on any website, and not much on Google either. I will be putting one (in excellent condition) up for sale soon but don't know what a good reserve price would be. Any ideas??
Put it up for no reserve and it will sell for whatever it is worth.

The is info in the blue book, but you have to pay for it.
$200 start, $400 reserve. Nothing special about the Dynaco 80 sound, so it really is not a 'classic'.
