The Mark V 35 has 4 x EL84 power tubes. Can someone please confirm the positions of the pairings. Thanks.

Usually it would be inner pair, outer pair.

Looking bottom up from behind, left to right
V8 V10 V9 V7
35 Watts = V7 - V10 Pentode
25 Watts = V7, V8 Pentode
10 Watts = V7, V8 Triode

Thanks guys. It hadn't dawned on me that the 'valve numbers' on the Mesa manual page effectively also tell you the pairings. In other boogie manuals I'd seen, they indicate tube positions under the illustration. Your help is much appreciated. Clive

I ended up purchasing some Mesa branded valves, which purely by co-incidence where the same colour code as the existing ones. Meaning no re-biasing and everything just worked fine.
