MH's ideal coil and voltage question

I'm returning to some cool audio design.

What are you makin'?

Perhaps it will have a tone control circuit using, as is often done, a simulated inductor circuit, i.e., a "gyrator" circuit...

After all this, I can't imagine having to explain that one...

Haha,

I refreshed my memory about gyrators the other day as another idea to perhaps help elucidate on the inductor discussion here, but I soon came to my senses

Breaking new ground with a guitar amplifier design. MOSFETs rather than tubes. Could use your help with a few advanced questions if you wouldn't mind.

.99,

I always wanted to try switching out the outputs in the larger bass and guitar amps with MOSFET's. 6L6/6550?.

I love analog audio design,  I miss the old discrete stuff, like Flickinger, API and Sphere consoles, etc (with the Sphere Eclipse C with their SPA62 discrete opamps and passive EQ circuits sounding the best in my opinion).  I also miss discrete analog tape recorders like the Ampex 440 and MM1200 series.  But the current 2" tape prices and availability, wow...  Anyway, those were the days.

As for your project, you could ask but I am now on page 28 and counting of a document for a client and I have not even gotten to inserting graphs or images, and it was expected over a week ago.

So, the timing could not be worse.

There is just never enough fun...

It has to be an Old School gyrator, see attached.  If the gyrator is post-1950 then it is suspect and could have been corrupted by the PTB.
