Radio Newbie in need of some guidance for an 84
#31

The plot thickens! You should not have 0 ohms between 6 or 7 to 8. You also reported the center tap (8 ) to chassis as 0. As indicated this should be around 320 ohms via the resistor off the CT to chassis. Makes me think as indicted to pull the transformer wires off the chassis for the 5V line, the HV line and the center tap and make readings from the various to their partners and also to chassis ground to see if we have an internal short on the transformer and all the windings are intact. I suspect some wires messed up or the transformer. Once you identify each winding and confirm continuity also do a check between the 5V winding and the HV winding to assure no short between the two.
