#1 Suggestion for CCS at 140mA

As per the title, does anyone have experience of CCSs running currents in the 140mA area?
I’ve usually gone with the K&K kits, but Kevin says they are prone to oscillate above 100mA

What level of voltage are you using with the CCS Max ?

You could always parallel a couple up.

Thanks everyone.
This would be used in the supply of a push-pull pair of 6b4g. I want to try a shunt regulated supply, with this CCS followed by a string of zeners as the shunt element. Basically a straight copy of MJ statistical regulator.
120mA for the pair of 6b4g, maybe 10 or 20 mA through the zener string. Voltage drop across the CCS will be not much more than is needed to keep it operating happily.
