The tube in my Blast City just died (Toshiba A68LBT696X) and I am trying to figure out if the tube from a 2930 (Toshiba A68KZN696X) would work with the 2931 chassis. Any idea? Thanks!
 
I think that combination has no problem.
My own Blast monitor is same as that combination.

However If the MS-2931 chassis came with A68KSM696X, exchange of heater register is needed.

Thank you! Just to verify, since my 2931 came with A68LBT696X, I shouldn't have to make any modifications to pair it with A68KZN696X?
 
I think so.
Your 2931 chassi's heater register on R732 will be 1 ohm ( Brown, Black, Gold, Gold ).
If so, you don't need to exchange.

Ok I'll have to check that. What about the physical fit of the A68KZN696X in a Blast. Does it have the save curvature as the A68LBT696X or will it have gaps?
 
What about the other way round: Will a 2931 tube work with a 2930 chassis if all I care about is 15KHz?
