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 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.
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?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.
oh yeah it’s dead and that is what took out the tubeA68KZN696X have the same curvature as A68LBT696X.
By the way, have you confirmed that there is no problem with your MS-2931 chassis?
This is because a faulty chassis can break the tube.
PSA: MS293X, faulty chassis can break the tube
