Hi Mastertech,

It's the input bias resistor bootstrapped through the FB C, OK?

oh, yes it is a simply magical revelation....

Cheers,
Greg

The give away that this posting was not meant seriously was primarily that the poster was Amplifierguru of whose views I have some inkling. If posted on certain other forums by certain other individuals or reviewed in certain publications (none of which I shall mention), I would have interpreted it as having not even a hint of irony or satire but as written in complete earnesness.

Indeed, for the first two sentences I thought he had simply gone gah gah like so many others. Truly, I was feeling something like the concluding scene of "Invasion of the Body Snatchers" where the last survivor screams into the cammera, "RUN, YOU'RE NEXT!!"

Greg guru,

This hearing aid idea is fantastic !

Imagine we have a pre-amp, a power amp and now a post amp. I have some really good ideas that I am currently investigating. I am talking to my mate Albert at the patents office who is going to try to fast track some of my brilliant enhancements. Funny man, this Albert, all he talks about is being caught in a feedback loop of the space-time continuum. Crazy. As soon as he gets his finger out I'll release my plans. Hint: It has something to do with a "golden ear" extension to the hearing aid, an exact replica of Mozart's ear or was that Beethoven or Van Gough, maybe celebrity ears.

Thanx Sam, you're too kind.

Hi Greg E,

Revelations abound. Your Albert sounds like just the sort of contact I could do with to protect my Luscious amplifier.

Just imagine the Luscious amplifier hearing aid with an external water cooled heatsink and thermocouples for Tsense and recharging the LI battery at night.

It only gets better

The bootstrapped input is mentioned in Self's book but no mention of any sonic qualities. Should be interesting to try out.

I like the output coupling capacitor on the ground leg of the load.
If the outer layer of the cap is grounded ( -ve I think) it would keep it at zero potential and prevent any RF pick up. If RF pick up did create a problem on such a large capacitor, this scheme might be useful. Might be worth checking out .
Cheers.

Thanks for your input ashok, I will be doing an extensive a,b,c,and d comparison double blind on aformentioned mods to ensure we are indeed going forward in our undying quest for audio nirvania - with some help from my mate with the 'earing aid after the throbbing subsides.

It's exciting times

Cheers

Time to hijack a beer truck. There lots of enthusiastic company !
Need lots of 'bluids' to lubricate the gray cells. They have lots of work to do.

Maaate...I'm soooo sorry, what can I say, you weren't quick enough.

I've all ready got a patent on an almost identical amp (now) called the "Absolutely Stupendous" amp.

I found hearing aids work best with lots of ear wax, you need a perfect seal. (pat pending) I was going to try bees wax but their ears are so small. Candle wax is OK but difficult to install.

Love bootstraps Douglas Self wasn't overly impressed with the way bootstrap input measured, sort of implied it wasn't worth it, but true, he didn't say anything about how it sounded.
