[Heathkit] SB610?

[Peter Markavage]

Check the tube (6J11), check the tube voltages, check the tone level and
two-tone amplitude balance pots, check the components in that circuit
area. Maybe one or both of the phase shift networks are bad. Lots of
things to do and check before one runs "out of ideas".
