ANNOUNCEMENTS

***Harbach Electronics Back Open***

15 October 2021:  Thanks to everyone for the calls, email, concern and patience!  I am ready to re-open and the website ordering system has been reactivated.  I will do my best to get orders out as I know it will be busy!  There are still a couple COVID-related supply issues I am dealing with.  Right now I am unable to find a new supplier for fan motors for the FM-200 and FM-220 kits and for relays for the RY-200.  Due to these supply issues, those kits are not available and have been temporarily removed from the website.  When these parts become available they will be added back to the site. I am also still waiting for a new telephone line to be installed as the old one was damaged beyond repair.  Until the new line is installed, I will not have telephone service.  Please use the email contact form on the website for now if you need to contact me for questions or technical support.
