Denny was on the ground and running with Cary even before the banks closed
up Amp Supply. He even built the LK-800A at Cary for several years. I
wouldnt be at all suprised if he still builds a few to order.
Im glad for him and he always treated me well. He has found his niche and
its a lot more profitable then dealing with cheap hams!
