Ccs

[Jack Thomas]

I've been searching for a site or information on Gary Pimm's CCS's outlining how to calculate circuit values for specific loads. Can anyone please help? The attachment will be the victim of the CCS.

hi here is:

[jeapel]

here is the guide

[jeapel]

other option are:

C4S CCS from bottlehead company

and cascode with DN2540 (i don t try)

but i prefer the sound of C4S over Gary

[jeapel]

i forget :-)

the good point for Gary ccs is the mu-follower output
for low zout and very good bandwidth to drive next
tube stage

I would use one with Leds instead of 1N4004.

Hi Ryssen,
I got oscillations using the scheme with two LEDs in series. It was cured using a 1 kOhm resistor instead of Led1. I then discovered that Morgan Jones has done the same thing.

Here is mine:



You may use a P-channel FET instead of the upper transistor.

I got oscillations using the scheme with two LEDs in series.

I didn´t
done several of them.Know meny people done this.How did you notice that?

Tried one with a zener diod but strange noise at high frekvensys,Leds sounden much cleaner..

Wavebourn:How do you calculate R2 and R3 in your schema?

Hi Guys,

Walter Jung just published I really nice article about CCSs in AudioXpress. I recommend everybody to take a look at it
