Colin why such low input levels?
The silver switch has a green ring of low level LED light when on the M40 is up and running.
Hi Colin
Sadly your health and resulting problems are much worse than I imagined. It certainly makes you think.
I'm even more impressed by ability to design new amplifiers and ride a bike.
Sending my very best wishes to you!Hi Aspro,
The SECA or single ended class A I have used is based on one I did in the late 1970,s, and it is nothing like the over complex Quad design which is not a SECA design.
And it is not current damping either sorry.
Th BW on the devices I use is very wide up to 140MHz I do not allow the amp to see this because Taxi driver would blow you speaker, so I limit on the input the BW. But this allow me to keep the slew rate high in the amp, less phase/timing error.
As to my health I had major heart operation now fitted with mechanical valves and man made aorta, this was followed after about 3mth with a stroke, this caused me to loose speech and walking , right side damage.
Wheel chairs I hate, I tried and tried to walk and talk it was a long time to get it right, now I walk with a stick and fall over a lot, a hell of a lot.
My right thumb is not good, my speech has improved but some word I can't say.
But my brain seems to still work, so I was not going to be a cabbage as the other poor souls where in the hospital. Now I live in London not my beloved Somerset I have a log cabin run on solar, insulated and it is my play room, I do a lot of R&D and not all on Hi-fi.
Walking long distances say 500M is a struggle some times, so I got a electric bike with stabilizer wheels this is great fun and I get some exercise .
The TQ directors made the whole thing worse after I got sepsis by forcing me out of TQ by bulling tactics. Leaving me homeless and broke. So my mental health suffered to, but good loving friends saved me and I thank them everyday.
