[volt-nuts] Solartron 7150plus - Chasing AC gremlins

[ed breya]

I would first look at the electromechanical aspects. Are there any 
relays or connectors in the signal path? Next would be any device 
sockets - they can be exercised by rocking the parts a little. Next 
would be to inspect carefully for bad solder joints, corrosion, and 
signs of physical damage. Then consider the actual electronic components.
