Simple cathode CCS

Klimon · 20th June 2007, 06:51 PM

Hi,

Any suggestions for a component for ultra-cheap and simple cathode CCS? Current draw is 25mA, ca. 15V per tube.

LM317 is easy obtainable here (my local electronics store can supply all Farnell-parts), stuff like 10M45 or DN2540 unfortunately not...

Diyaudio / Gary Pimm / Machmat CCS are probably better but I'ld like to start cheap and easy... If Farnell has alternatives for Lm317 I'ld be interested to know

Did you have a look at diyAudio's CCS? Darn cheap!! And works great.

Would you have a link please, searching with the keyword 'diyaudio' isn't easy

I have the PDF manual that planet10 (dave) sent me. fire me an email and I'll reply back with it.

The LM317 works very well in this application.

Arnold, I sent you a PM for info on the diyaudio ccs.

Shoog, I'll probably end up using LM317 for this project, it's noted.

Thanks,

Simon

Are these DIYaudio CCS boards still available? If so, who is selling them? Please let me know, you can PM me if you prefer.
Thanks, Daniel

Check with Planet 10 to see if he stll has any left. If not, drop me a note and I'll fix you up.

Hi Shoog,

Does the LM317 CCS need the cathode bypass capacitor? Actually I don't like any bypass cap at all! Thanks.
