Hi , I have a Concordant Excelsior with the Explicit Power Supply . On the Exlplicit I have there only appears to be one half of the valve in use and Doug added a voltage regulator and capacitor to supply the voltage to the output socket directly from the regulator . So on the HT supply there are 2 220uf 400 v capacitors and one 100uf 400v capacitor . So my first question is has anyone else got an Explicit like this . Due to illness I have lost the valve that was in this and I’m trying to determine what it should be . If no one can help me with this I’m fortunate to have Dougs official circuit diagram so I can change the layout to correspond with that . If I go down that route I need to know the wattage of the2 22k resistors that Doug used . Can anybody help with this please . Many thanks Dave
