The Chet Baker AMP!

[Stee]

see this NEW idea (from Catalin)
is a CFP Driver
ideal for listening to trumpet
thanks to an extraordinary speed

design come from Rotel RB976 MKII
final stage are the famous 2SC5200 & C

Stee, that output is nothing new, first used in 1966, the triple darlington rotel uses is just as good if not better. Why dont you get a copy of D. Selfs audio book, you can learn a great deal from it.

I just optimised for my input impedance and a better thermal function.

Thanks Lineup, Welcome back

 

[Stee]

ok thanks

is not a new idea
also there is a previous forum
http://www.diyaudio.com/forums/showthread.php?s=&threadid=135535
but i'm not sure that solution was tested by true sonic performance

Stee that type of output is in use by many, have a look at Harmon kardon amps, some even from the late 80s. Like I said it dates from 1966. The BJT mosfet cfp you have there was proposed by JLH as being a superior sounding and dates from 1977.

Hi, lineup.. Stee could google that book as it seems google
cares not about IP..
My "WWW" has changed and a LOT (1.2TB)of stuff is in there,
but not Self's book. He is a active member here and
I would of been redfaced if was "doing" him like that.

If I wrote a book, I would want it to be read.
Not just by some few that wants to spend their money.

I do not know if Douglas Self minds too much that old book
becomes available to many happy diy audio readers. Even for free.
We would have to ask himself.

Here are educational writings downloads on Audio Amplifiers:
