** You need to check out the twin RCA plug lead that connects the reverb
tank to the amp chassis.

Make sure the plugs fit tightly in the sockets at both ends - use pliers
to gently squeeze the outside contacts inwards if they seem a loose fit.

Also apply a little WD40 on the parts with a small brush if there is any
sign of dull corrosion on the parts.
