I believe the tubes you seek are the dreaded and desirable 6LQ6's. TV sweep tubes from the past.
However, if you have some basic electronics knowledge and can use Google there is a mod out there to convert the amp to use more available and cheaper tubes.

Be advised that you must use due caution when working on any tube amp. Voltages inside are lethal. You must discharge the large filter caps with a 'chicken stick' and of course unplug the amp. Have fun . . .
4 driver tubes are 6jt6a. 4 finals are 6lq6/ 6je6a or 6mj6 (heavy duty 6lq6). 6jr6, 6jg6a tubes will also work as drivers, but thier filament current is a little higher. HIGH VOLTAGE IS LETHAL! discharge large capacitors to ground with a chicken stick as stated in other post.
