Have waited looooo0oo:eek:00oo:eek:oo0oooo :yell: oooooong . . .

Maybe, the nose of Nelson is too high to look down at it . . . :D
I have no more patience . . .

Here it is . . .
Initiative is the Pass cascode design . . . I give her a name, Zeny. :)
Expecting a beutiful result . . .

Any comment, advice, opinion, plz?

Dr Pass has no experience at phone amps,
they are a completely different ball game,
your amp looks really good!!!
may i suggest
you bypass the cap of the cascode transistor with a 100n cap

kind regards

:clown: I somewhat have to agree with mastertech here .....

You dont go to a car dealer, to seek advice,
when you are going to get yourself a bike.



I know for sure, Dr Pass hasnt yet forgotten how to smile ;)

A big :) smile :) from lineup
 
This is my last 'thread divertive' comment (sorry JH).

I think people are too quick to speak on Nelson's behalf. If he has a comment, is it not up to him to make it? If he has no comment, is it up to him to be silent? For all you know he could have been 'kitchen tabling' phone amps for 25 years and very well could be an authority on the matter.

I take it all back if you are in fact "Robin Masters":clown:

Sorry jh6you...carry on.:)

A girl, my daughter-like, very much likes the sounds from both my new Krazy (JFET cascode) and tooboo phone amp . . . :) . . . hmm . . . okay . . . I will make a phone amp which should be very nice for her. And, one for my naughty boy, one for his brother and one for me myself . . .

This is a very initial design.
I am now trying a hearing process through this thread . . .
To collect yr positive and negative feed-back . . .
Will reflect all the feedbacks and build it . . .
Then, a period of listening test . . .
:)

May I add my favourite link on Pass Teaching DIY low power amplifiers:
( even Dr Mastertech might catch one or two good thing from this excellent tutorial :) )

An externally hosted image should be here but it was not working when we last tested it.

JH6You,

isn't that called series production ? :clown:

I've got a few hundred 630's left, thought of using those to try your Zenpy. Are you going for PTP again, or for a board layout to supply all of China ?
The Zen master is probably still coughing in his Edsel.

The PS looks nice.

You know JH6You, once every couple of months i go to my favorite Chinese superstore for spices, boxes of noodlesoupe, the works. They carry fresh fish in tanks you don't even desire to see in a zoo, let alone on your dinner plate. Such a store is pure poison for me, i always stay there way too long.
Anyway, there's a whole showcase of Chinese medicinal stuff there too, from ointments to ground Rhino doodoo for willy business and the likes.
Personally, i have yet to meet a sneezing, coughing and hanky filling Chinese person. Interesting. :clown:
