amp repair

[tom1946]

Hi,

anyone know where I can get a Markbass amp LM3 repaired around Teesside please?

It crackles and sounds a bit distorted.

Thanks.

Tom.

Real Electronics in Sheffield are the authorised service agents, but the repairs (depending on the issue) are generally more than the cost of a 2nd hand LM head.

Check out local music groups on social media and ask for amp repair recommendations. 

I've had a few repairs done by local electronics engineers who work out of their garage.

Does it crackle all of the time. One of my amps crackles a bit but if I adjust the master volume a smidge it stops doing it. Probably needs pots cleaning and a bit of a service.

Just needs a volume pot, you can't buy them though. It only crackles when moving the volume, if i fiddle with it I can get it to stop for a minute then it starts up again...

Or maybe you can......

And apparently if you remove the knob, there's a tiny hole which you can spray contact cleaner into, although some people don't recommend it.

However, I've just tried to pull the knob off mine and it's super tight so I can't check that.

Ha, just tried to remove the knob on mine and that won't come off either.
