OK I replaced the 2nd IF transformer and got it working. I have radio but...

I do not understand the following. If it is normal or not for this 46-1203 ACDC Radio.
In the schematic it has the loop antenna going from the tuner through the 2 ohm loop then to a 35 ohm coil and to chassis ground. I can only get reception when I short the 35 ohm coil to chassis ground.

The other 2 things I noticed is the chassis measures 120VAC to safety ground and 100VDC to safety ground with the plug either polarity..

Is this NORMAL or is somthing shorting to the chassis??

Anyway I have stations now but only when I short that 35 ohm coil to the chassis with just the 2 ohm loop between the variable cap and ground.. I do not understand why this is?

THX

Thanks Morzh. So it appears I did wire it incorrectly and I have to switch the wires between pins 2 and 4.bobclausen — 09:24 AM
