Sorry, but the IRFI640G is known to sounds veiled.

You should try to fix your mate's hearing aid first and then look for a replacement part for this FET in an otherwise very promising circuit.

Very interesting, but when does the life size, 50W at least model comes out?

Gee... Greg, how would I do who lives in Northern part of Europe, consult Mr Corioli.. or should I stick to my Tibetan monks?

Edit: Patents, patents... any number and where registered, USPTO?

Hi all,

Well what a difference a day makes (hmm... good name for a song!).

While deep in meditation last evening a revelation came to me - bootstrapping the input resistor to ensure a more manageable input impedance so the wondrous nature of this amplifier can be sharedby more - and not confined to just those with buffer drive.

Magic happens! The soundstage just exploded! It's awesome.
I was taken aback that I could actually improve on such a honed pinnacle design.

We just never stop learning.


PS My poor old mate has had to go into hospital to have his 'earing aid extracted using keyhole surgery.

Default Sorry, Guru, but...

You've been fooled by back EMF! What you are listening as a stage is echo!

Just see the path - 2k, 100mF, 2k - and input again!

Or does echo improves the soundstage? Have to check it.

Well, there's your problem right there. All this new-fangled technology simply can't hold a candle to the classic ear trumpet hearing aid design. If your friend had one of those, he'd be experiencing sonic euphoria!

Hey

Are you high on the fumes that your last amplifier prototype expelled while exploding?

That's what I get for trying to make a SPLIF power amplifier. I think the BONG topology would be better

Hi Jorge,

Is it echo - or simply reverberation! I like it. I like it a lot.

Andy,

Yes he used to have a ear trumpet but people were beginning to talk so he invested in a solar powered LI batteried mini unit. So I now know he was prone to long nights of aural euphoria!!

I've a sneaking feeling there maybe further revelations as I peel back the layers. Any ideas.

back to the meditation.

Cheers,
Greg
