Hi Bill and the many other members of this list,

because I'm a retired professor (no, not for electronics but for
neurophysiology/neuropharmacology) I'm a hobbyist, only and develop and produce
items for my own fun. My prime attention is making these things in my eyes as
nice as possible, regardless of the effort I've to spent. IMOH, most important
is a nice optical fit to the vintage gear, full reversibility, AND e.g.
replacements have to be BETTER than the vintage originals.

I'm happy if others like the devices, too. From time to time I offer items for
sale. As I prepare the devices by myself I miss this time for the many future
projects in mind. Besides the things of interest for the auditorium of this list
I'm also heavy engaged in tube testers. Here a recent publication:

So, if you need any of the devices I'm preparing send me an email and I'll try
to fulfill your request as fast as possible.

Best Regards & vy 73
