Ampeg SVT-610HLF with noise on (disturbing mind)

OH NO! Tell me you didn't use WD40 to clean the pots! If you did they are all ruined!

 

Regular WD40? Probably ruined the pots, possibly damaged other components. Regular WD40 should never be used on electrical or electronic components, only mechanical.

WD40 contact cleaner? Might have a fighting chance.

 

Yeah, you have almost certainly created new problems in addition to the problems you originally had.

If you don't know that you are doing (obvious), why did you think this was a good idea? There are also high voltages inside that preamp, spraying anything that may migrate can also attract conductive debris which can cause other problems as well as create a safety hazard to anybody servicing the preamp in the future.

You have taken what would have been a simple, inexpensive repair (for a QUALIFIED service technician) and turned it into something quite the opposite.

 

No I am not a professional player. I've never wanted to be one - I enjoy my music too much. I do consider myself professional when I playl.

I think that maybe we are enjoying is possibly a language barrier. The controls that you rotate are called Potentiometers, pots for short. A button is a switch that you push to turn say the amp on or mute it for example.

You should never, NEVER use WD40 on any electronic device.

Did you open the chassis of the pre-amp to clean the pots? What did you do?

Oh and no Hugs please - Social Distancing!

 

NO!

The only stuff you should use is Deoxit D5 and then just the tiniest amount possible.

 

You say the cab makes a noise "with nothing connected"? Do you mean nothing is plugged into the jacks on the back of the cab? If that's the case, there's an animal living in your cab.

 

That is an electrical contact cleaner and shouldn't be used on electronic devices.

 

Ugh, stop (alto). You are just going to make a bigger mess out of what you already have. It's time to find a QUALIFIED service tech before you end up with a preamp that's no longer economically repairable. You may already be there, but that's just an educated guess.

 

Ah! Got it.

Welcome to TalkBass! Good luck with this.

 

and in the future, don't ask that friend for advice...

 

Yup, that's what he said

 

Did you only spray the SVPCL and not the SVT?
If so, remove the SVPCL from your setup and get it seen by a tech.
You can then plug your bass directly into the SVT and then connect it to your 610. If the noise remains, try a different cabinet and/or cable.

If you sprayed both the SVPCL and SVT, take them both to a tech.
