I've been playing around with an old BMR and it all works except the reverb (even the vibrato still works). I've pulled out the reverb tank and opened it up. Everything looks OK. I've replaced the footpedal and associated connection cables. Any ideas about what may be wrong? Thanks.

Maybe a bad 12AT7 driver tube or 12AX7 recovery tube?

Thanks, BMW2002Ti. I'll take a look at that, but the tubes are all relatively new.

Never mind "looking" at things.

Have you checked the continuity of the reverb tank and cables with a meter?
