I can honestly say tube amplifiers and the maintenance of them, are definitely more within Scott's abilities, then our solid state VDMOS venture was. The minute I heard about Harbach, I was surprised that Scott had not already arranged for a seamless transition of the business.
Being as dependent as his business is on obtaining these amplifier rebuild kits, I see taking over Harbach as a natural fit. Especially if he has sole control of it. When something is within his ability, or within reach of obtaining it, his motivation can be unmatched.
To be fair, doing business with someone, it's not the same as being in business with someone. The skill set required for each, are different. In other words, you can do a great job doing business with your customers, and not be so great at being a business partner.
