It seems we were through a similar senario, on this site, a while back. Or did I see this on another site???? While I think this problem started out with a single problem, that of the electros wrongly wired, which somehow overloaded the dial lamp, (the weakest link in the filament circuit) it does nor surprise me that the demise of 35W4 would follow. It seems that the way the circuit using a 35W4 with its tapped filament is designed, the loss of the 35W4 was destined to follow. This can and maybe always, eventually cause the loss of the tube itself. So! If the dial lamp has not been replaced, do so immediately, or you will possibly lose a third 35W4 in the near future.
