'It seems to me that the polarity of the transistors is reversed in this schematic.The other thing is that the output impedance is no better than that of the raw DC supply. If I'm not mistaken'
The transistors are PNP types , I think I drew the schematic correctly but I do get a bit confused sometimes with 'upside down' electronics ;) The output impedence should be lower than a pot which is the intended purpose . I had not thought about choke-input bias supplies before . I suppose the value of bleeder would allow a certain amount of bias variation
cheers
