Vintage NAD 3020 problem

[Duffin]

Hope this is the right place to ask.
I have a NAD 3020 amp (bought in the 70's) and use it sparingly now.
I just turned it on and it played fine (tuner) for about a half hour then shut off, power out and the tuner connected as well.
The tuner is fine when plugged into the power bar.
I have tried the amp plugged into other power source still no lights.

Any idea as to what caused this?
I have a NAD repair close but wanted to get some idea before I go.

Thanks
DuFf

If he doesn't show up on his own, send a message to Leesonic. He's got more time under the hood of a 3020 than anybody I know.

Sounds like your power switch has gone bad, especially if the tuner was connected to the switched power output on the rear. You can get new ones from Mouser, I would recommend a new spark suppressor as well.

Search for threads started by me in the solid state forum, and you should find a couple of examples, complete with part numbers.

if it has a power plug with a fuse check it . like if in uk .

Yes, check thy fuses and power switch first. Not unusual to see issues with either.
