Well they ain't that little. The EF91 pentode is the
large tube in the centre. On the left is a 9002 single triode, to the right is a rather corroded 7586 single triode Nuvistor.
The tube at the front is a 6111WA...this is a
twin triode ideal for the smallest of NBTV CRT-based displays. It's ratings are similar to those in the ECCxx range including a plate dissipation of over 1W.
I've changed my mind over which tubes to use in 'The Brute', I'll still be using EF91's for the 5" deflection but for the 1" tube I'll use the 9002's...just for the heck of it.

Sorry for the poor focus, that #@&! camera again!...and it was at its smallest aperture, f11.
