For a minute I almost thought I saw a surface mounted component in one of the photos, displayed on the website linked in post #15.
It's where the vertical blue line intersects the horizontal blue line.

You are correct we are using some 1980's technology these days.😀
we all know here who Wayne is, so nothing new with that praise
though , it's good for sales
🙂
meaning - more greenies for Papa and Wayne , money means freedom, freedom means more of their time spent on Greedy Boyz
win-win

Muses volume IC?
Did I every mentioned that Wayne once designed a superb discrete transistor
volume control? We applied for a patent, and the years when by, and when
Wayne inquired as to the status, the patent was immediately denied, apparently
out of spite by the examiner.
Another reason why I gave up on the patent office years ago....

I believe you mentioned that , and residents know it was a part of X0 preamp ,at least (lazy to check other ones).
evidently , Wayne is also having all the fun , while leaving Who's the Smart Now?!? role to a guy with crazier Green

I do not see any measurements here?
The original review had the measurements from John Atkinson.

Is that a 2-stage shunt attenuator? If I can count 6 steps followed bv 10 steps.
Here is the schematic for the X1 volume control. 32 step balanced shunt.
It was similar to a RF attenuator circuit but used less parts and less supply voltage. Transistors have built in base resistors. It worked well at the time and certainly sold well.
I still remember the patent examiner asking how I got his phone number.
His assistant was appalled at the time delay and connected me.

And all the power amps as well.
Wayne, how many years have we been working together? 30?

Thirty years this year Nelson.
These products are a group effort. Sometimes the basic design seems like the easy part. Refining it is the time consuming part.
And 3 months, 4 days, and 45 mins... But who's counting? 😉
We are lucky and fortunate to have you both interested in helping revitalize the DIY community!
