Newly CCS circuit from Pimm
Anyone try this new CCS circuit from Gary Pimm? I'm planning to use this circuit in 12B4a preamp, the operating point is Vp=100V, Ip=30mA. So,
Q1) how can I choose the value of R1 (=8V/30mA??)?
Q2) LND150 is not available in Hong Kong, any substitutions can be used?
Q3) How much voltage drop across the CCS?
Thanks in advance!!!
