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).

I have done a followup with Technics Parts agents in the US, they will get back to me and then me to you shortly :) A vote as FixYa would help improve my ratings. Thanks

SOURCE: amp cuts out
The fan is ageing and putting noise on the protect line. Replace it or put a 100 uf cap across the fan at the plug. Beware polarity is marked wrong on p.c.b.
