No sound coming from the speakers only. Cannot understand why they worked perfectly a day before I relocated from last address

SOURCE: Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem

This can be as simple as a poor connection somwhere in the voltage regulator circuit or a defective driver transistor or output transistor. In any case, this is a simple repair for any shop that works on vintage receivers. If it is the outputs, that will be the most expensive repair from a parts perspective. The outputs will cost in the $5-$10 range for each one and it could be 2-4 pieces. If you wish to attempt this repair yourself, you will need a multimeter that has a diode checker. Let me know and I'll provide additional details and instructions.

If you are not looking for a warranty repair, any shop that handles high end audio repairs should be able to resolve this for you. Before you ship off the pre-amp, verify that it is, in fact, the pre-amp that is defective. The initial stage of the power amp can cause this as well. Try hooking up another pre-amp instead to verify the problem location.

Keep us posted,

Make sure that you have the correct input signal selected.
Also, check if the sound is not muted.
If you have a multi-room speaker switch, make sure it is set correctly to main speakers.
