SOURCE: Technics SU-V2 keeps cutting out
An amp will cut out if the output protection circuit kicks in. This circuit compares output power against the preset level. Each channel has it's own, independent protector. There are calculations that can be done, but for a novice the rule of thumb is to "never use a speaker with a power rating less than the amp AND a lower impedance than stated". Typically using a 4 ohm load on a 8 ohm system is inviting disaster. Even if the system does not become a smoke generator, you might notice that though "louder", the sound quality is deteriorated. Many "audiophiles" often hook up some combinations of speakers to have "surround" without really understanding that the collective impedance actually changes (generally lowers).

Problem with older equipment is that mechanical switches corrode. Try some tuner cleaner on switches. One side cutting out may require the speaker leads (inside the cone of speaker) to be re tinned. Old speakers and lossa mileage cause solder to break up into powder. Re tinning the flexible link (looks much like a wick) allows that electricity to get into the speaker coil. If all else fails those old TV repair shops actually do have real techs that can fix it. Not like the current Geek Squad type of replace replace reboot replace type of tech. Good luck. Ed
