[NJARC] BC-348Q Power Questions(2 of them)

[john ruccolo]

Hi Scott,

How did you finally get the B+ down in that power
supply? Hopefully *not* by overloading it with a
low-value bleeder resistor. Do you know how much B+
current you're drawing?

I thought you said you needed (or wanted) 250V?

BC-348's are fun to play with, aren't they?

Regards,

John
