That is correct. The 7A7 was in the radio when I got it 50 years ago. I read in some cases it can be used as a substitute so I didn't suspect it was a problem since it worked for so long but everything should be suspect now. I discovered one of the e-caps had been replaced before I got it and stuck under the deck so the tube was probably replaced back then.
