In Reply to: This would appear tobe quite similar to my PP-1C circuit... posted by Allen Wright on March 14, 2006 at 02:47:07:
Here is the actuall power supply used, including the actual measurements taken on the circuit. I got to note that the transformer providing 2X350V for the output stage, is getting very hot(touchable) after the first hour, as the unit is marginal for the current consumption.
Dear Allen, the CCS is exactly as in your PP1C, but adjusted with the small trimmer, for 28-29mA.As Peter said, as long as there is about 4V on the trimmer (and always is) the CCs works well, of course a more sophisticated CCS would be better but this is still an experimental design. Anyway I had an idea, what would happen if I attached another current source at the common point of the output tubes(where the 22ohm resistors join)?
