Good Morning all, I have just purchased a Kriesler model 540 of about 1938 vintage. I have the circuit from A.O.R.S.M but it does not show any voltages on valves, nor any resistor ratings. It is designated as "progectographic" . It also has a 6B5 output valve which I don't have. Any help would be appreciated. bowler |

It's a poor scan, but I can see some test points giving voltages. Other hints are the rating of capacitors and also the operating characteristics of the valves. Most radio designers stayed within those recommended valve ratings. |

Australian circuits & American ones tend to have many, inferior circuits when compared to many German ones. In most cases I use one watt resistors to get the voltage rating. B+ dropping resistors may need to be more. |
