I will try to keep the current count accurate.
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.
