If there is a socket for them, of course !
The Service Manual will tell you what those tubes are used for--

Those are the 6BJ6 tubes that are used here to provide AGC control and (hopefully0 make all records approximately the same level.
If the amp has been rebuilt and the old selenium diode packs replaced, the circuit should work.
"Gepettos" often removed those tubes to make up for lost volume in a failing amp or to make the machine blast at higher levels than it was designed for.
