With the circuit you described, with a new battery, you'll get around 0.13 A tail current and this current will drop over time. I'd be putting a 100 uF 20V capacitor across the 9V battery for noise reasons.Since your going to have about 40-50V across the CCS, I'd actually recommend a slightly different circuit using two series 6.2V zeners biased from the B+ with a 430K 1W resistor. There'll be about 8.4v across the bias set resistor.
A tail current of 0.17A bias point would be better.
Play safe and play longer! Don't be an "OUCH!" casualty.
Unplug it, discharge it and measure it (twice) before you touch it.. . .Oh!. . .Remember: Modifying things voids their warrantee.
