Thanks Ron, and now I'm paranoid about that grill cloth! Hopefully it survives. Hes going to remove the speaker (is that a plug on the back or just some unusual strain relief block where the speaker wires enter the chassis?) and ship that separate from the cabinet. The cabinet will be wrapped in carpet underlay and boxed.

Power supply it is.. an LM317 should deliver the required filament current which I calculate as around 680mA all up - does that sound right? Seems a little low but the 30 and 32 tubes only have a 60mA filament current.

Cheers

Steve
