Removing the 7Y4 and no sizzle does not necessarily indicate that it is bad.

Pulling the 7Y4 removes plate voltage from all the tubes, so there still could be a shorted 41 output tube or a short elsewhere. Reinstall the 7Y4 and remove the 41's and see what happens.

Did any of the tubes show a blue glow or sparking inside?
