Default Simple cathode CCS

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

Simon

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

Hi Shoog,

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