half the tubes check bad
#1

I got a 48-1263 some time back and yesterday I got around to recapping it. Someone had already been there and I only had to replace 4 paper/wax caps and both can caps and one 15K resistor that was reading 27K. Plugged it in and got nothing but dial lights glowing. I checked the tubes and 4 of the 8 showed bad or questionable. Is this likely or is my old Heathkit tester on the fritz? When I picked it up the owner had it turned on with the turntable running to show me "it works". I  immediately unplugged it and took it home, but could she have done something then that wrecked those tubes? Yes, I am very new to restoring radios. Help!
