[Amps] Changes at Harbach Electronics

[Geert Jan de Groot]

I think many of us know, and/or have used the amp upgrades from Harbach 
Electronics. There will be some changes, see https://harbachelectronics.com/

Let me add THANKS to Jeff for all the work over the years and I hope the 
progression of the disease can be slowed down or stopped.
