The cathodes are tied together on the 6G7A in the first two stages with 820 ohm resistors. This is very similar to having a 1500 ohm resistor on each cathode. The Bassman has a 1500 ohm on the first stage and a 2700ohm on the second stage. That makes the second stage a bit 'cooler' on the gain side form the resistance pint of view.
The BAssman has higher voltages to the preamp than does the Bandmastaer.
All of the 6G6 BAssman amps have the tapped treble pot whereas the 6G7A is the only 6G Bandmaster that has this pot.
So, similar but different right? I would figure the BAndmaster is just a bit warmer due to the resistance in the second stage and the lower voltages.
