[NJARC] Selenium Rectifier Question (Heath SG-8)

[TrainBee at aol.com]

Hello all,

    I am having a problem with my Heath SG-8 Signal Generator.  The fillament 
voltage is OK.  The other side of the transformer goes to the Selenium 
Rectifier.  There are two problems here.  
    1) I have no reference for the voltage that is going into the rectifier 
and what should be coming out of it. I am getting a negative reading on the 
input to the rectifier and a 400v +voltage on the output side.  Strange since the 
electrolytic is rated for 150volts.  Any ideas what voltage I should be 
seeing? 

    2) The output from the rectifier goes to a 1W 3.3Kohm resistor to serve 
the oscillator section.  With the unit off the resistor checks OK.  With it on, 
the resistor does not pass any voltage.  Any ideas of what is going on here?

    The Heath SG-8, uses a 6C4 and a 12AU7.  Both check OK.  The unit is 
wired correctly, double checked.  All of the other components check OK.  This 
leads me to the question above.

Thanks for any guidance.
