Avalon 737 sp help?

I have a avalon737sp that has recently stopped working.


symptoms: Turns on still, light up and all, but there is no sound on any inputs or out puts, and the meter no longer moves.




Any suggestions are helpful, I dont plan on fixing myself unless its possible, I just dont wanna get ripped of by the repair man.

thanks in advance.

Make sure that you have the correct input setting selected i.e Inst.-mic-line.

Sorry. No insult intended.
Under warranty or not I would contact Avalon first.
I have several pieces of Avalon gear and have only needed to contact them once. They were very helpful. I've read they may be a little difficult to reach these days but they're also known to go above and beyond when it comes to servicing their gear.
You're better off calling them.

this is a stereo unit, so:
if both sides dont work, i would suspect something common to both channels: a power supply issue.

so, this is a tube unit so there will be a single hi power rail (between 140volts and 300 volts so be careful, real careful) to power the tubes and there is usually a fuse on the ac side of this.

also, the 6 or 12 volt heater voltage that heats the tubes would cause both sides to go down. check to see of you have the tell tale amber glow of heaters in the tube.

there could be a soft start muting circuit that waits for a while when you turn it on so you dont damage something and then turns the rest of the unit on. Im not sure if it does, but those kind of tricky circuits are the first to fail.

those are the only things i can think of that would kill both channels completely without having to drop the unit from the roof.

hope this helps
