    I pulled my old brown Pro out of storage a few days back. The normal channel sounded great, but I couldn't get any sound out of the vibrato channel unless it was on 10, and only then very soft. I replaced the tube with one I knew worked (from the normal channel). Nope. I cleaned the pot with lube/cleaner spray. Nope. What gives?

    Any number of things................

    The key word that tips me off is STORAGE. Caps in amps are a use em or lose em proposition. All my amps get turned on for 5 minutes a day wether they get played or not. I would look for failure in one of your cathode bypass caps or in a resistor in the same circuit. Dirt or corrosion in a tube socket or input jack is a possible culprit as well. I would resolder every joint in the amp after I recapped it.

    Best Blues,

    Cookie, you may be seeing this amp sooner than you think. I can't find a repairman around here I trust.
