Yes;
The negative side of one condenser is supposed to be connected to the center tap of the high voltage winding, and not the chassis, that is the most negative point in the B- side. A lot make this mistake with replacements because most post war radios had their audio output stages self biased, via a resistor in series with the cathode of the power output tube or tubes, the set will hum like mad as a result. In this case it looks like a previous "repairman" stuffed a pair of twist lock condenser cans in the old clamps, and did not know what the cardboard sleave was for. You should see what some hacks did to house wiring back in the day.
