the Caniggia Connection

[Stee]

this schematic is similar to CFP but with common base input (good to avoid saturation) and with a little gain

 

[Stee]

better power with discrete opamp

it's also a good idea increase power with balanced configuration (need XLR otput on DAC)
very important tube preamplifier without NFB to expand signal and have a deeping scene

LSK 389

it's a double 2SK170
much better on mirror because more similar

I am doing something similar with a double CFP that is under development. Just I did not know about this Caniggia .

The other one that I remember was playing football in The magic Brazil team with Pele'.

really this idea comes from Mark Levinson's input (inverted)

common base VAS

is from Accurphase

better view

with op-amp

Is the red line supposed to go from the junction at the one 330R resistor to the other?

 

[Stee]

yes

see new zoom

better way @ 18V is balanced mode (domestic power)

 

[WuYit]

Stee,
input resistance is a nuisance.

 

[Stee]

Probably need a buffer

remember the CFP have a big sensitivity
