HELP! Nashville 112

[allan cook]

Can anyone help with a problem?
My Nashville 112 was fine last night. This morning it gives out a loud buzz when switched on. This is with or without my steel plugged in and even with all the knobs turned to 0. The amp has not been moved since last use.I have tried it in various sockets around the house. Bit of a mystery!

Any ideas gratefully recieved.

Phil, sound like it could be a mains hum. I had that with my Fender 15W. Try a different Power lead?

Thanks Jason
I will give it a try if I can find one.

You say Buzz, is it a mains hum (50 Hz) or a higher frequency ?

Try pushing a jack plug in and out a few times on the break points I.E. the Pre Eq patch sockets on the front, and the Power Amp in and Pre amp out ones on the rear..

Also do not forget to check the molex connectors.
Peavey amplifiers are notorious for the molex connectors giving trouble, some DeOxit will probably cure it..

SOMETIMES a hard slap with the side of a clenched fist can help, if it doesn't cure the fault at least it helps relieve the frustration somewhat.
BTW. If a hard slap DOES cure it, then the problem is a bad connection somewhere either a dry joint of some inter PCB connector..

Thanks Basil
I tried what you said but no joy. I think it will mean a trip to the repair man.

If the amp is under guarantee.. Take it back..
UNLESS your 'Repair Man" is au fait with Peavey amps I wouldn't recommend a local music shop.. Most of them just send the amp back to Peavey services anyway, they will charge you the cost of the freight/repair then add their 30%-40% and vat..
Not a desirable step.

The service dept at Corby is excellent..VERY quick turnaround..

Phil that sounds like it could be the smoothing capacitors, not a DIY job unless you are really good with electronics.

I've had to change the smoothing caps on my Nahville 400 about 4 times since I've had it. If you do change them make sure you get the right voltage as well as the correct capacitance. A giveaway can be if one or both of the caps are leaking. Plus they must be soldered in the right direction. (They are arrowed)

Thanks for all the great advice. Jason was the man! A new power lead and all is solved! How can that go wrong overnight???
Thanks again.

You want to try the bloody Greek electric grid, anything and everything can go tits-up during a
show and quite often spikes causing bad things to the amps and things !
