Current backlog (5/16/22): 10 networks.

I will try to keep the current count accurate.

I have completed all of my backlog except for 5 sets of CSW-450 networks. I am build these now. I hope to ship these in the net two weeks.

Announcement:

I have decided to retire from crossover network building. I will accept no new orders.

Between 2000 and 2021 I have built over 2200 crossover networks. I am burned out!

I am 75 years old and anxious to reduce my work load and do other things.

Parts, especially iron core inductors, have become nearly impossible to get. Substitutions have been just as difficult to identify and obtain.

Note that my telephone answering machine has been turned off and I will usually not answer. Your best bet to contact me is by email (ak@alkeng.com).

At some point I may resume building to a limited degree but for now I will only finish the orders I already have in my backlog.

I will stand by what I have built. If a problem with one of my networks arises, I will service it.

Now, the inevitable question: Would you give me the schematic diagram and parts list to your designs? The answer is absolutely NOT! I learned the hard way that others will not build my designs to my standards. I do not want the "credit" for networks built in my name that do not measure up. Worse yet are those attributed to me that I did not build. Worst of all are those who think they know more than I do and act to "improve" my designs with extravagant parts or other changes! Experience showed me that even my kit networks, including step by step instructions, were often ruined with the best of intentions. For examples, look at my Question and answers page. DIYers: FORGET IT!
