The power on my Technics Amplifier SU V4 comes on, but no clicking sound is present. The amp also produces no sound. What do I need to do to get the amp in worker order again ?
The clicking sound will be a relay for the protection circuit. That could be faulty, but first check out the main devices on the main amp section. Those attached to the big heat sink. If you see a single IC amp that could well be faulty.

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).

it is relay control the output you can changed in near electronic service center.
SOURCE: Hello I have a Technics SU-V45A amp, it's about 18
See there is a problem with the volume conroller as it is 18 years old the controller has worn out replace the volume controller with a new one and you will be able to enjoy great sound again
