Support / Spare Parts
Hi, I am Dan. For over 20 years I worked at Emtron with Rudi Breznik, building and testing linear amplifiers. I have worked on 1000 amplifiers. If you own a DX-1, 2, 3, 4, chances are that I have tested and adjusted and partially built your amplifier, years ago.
Sadly, Rudi has retired and Emtron is no longer active. I am building and selling a range of Radio / Antenna switches, using Emtron as a brand name. These are current products, but they have nothing to do with Rudi or the old Emtron. If you buy one of my antenna switches, the invoice will come from ADD OMMUNICATIONS, which is my business name.
I am happy to provide a reasonable amount of free advice to all owners of Emtron amplifiers. This would be mainly by email, with the occasional phone call. If you are skillful in High Voltage, High Power RF circuits (or if you have a friend who is and can help you), I can guide you in fixing your own amplifier.
Please use the contact form to send me a message and I will answer to your email address. Please write in Subject: DX-? amplifier. I do not read messages unless they refer to my antenna switches or Emtron amplifiers.

B. Limited stock
I have limited quantities of some items. When they go, they are gone.
C. Current (more or less)
These are parts that I can re-order or make myself, mainly electronic modules.
1. Control Board.
I’m considering running a small (last ever) batch. This would be based on the last version (AMPC5.3) with some minor improvements. Compatible with all Emtron amplifiers, DX-1 to DX-4 (except the first about 10 very early DX-2).
I’m seeking expressions of interest, so that I can decide on a quantity and work out the price.
If you are interested, please use the Contact form and write “Control Board” in the subject. Obligation free. Thanks.
