Iam working on my first radio project , It is a Phico 39-71 farm radio . When I hook up 90 volts to plate I get 90 volts to plate ,then I hook up 1 and half to filments ,And the voltage on the 90 volt side drops to 14 volts .That is not supposed to happen is it ? And if so .can you explain why ?Thank you Henry
