I wonder if anyone can help?

I have a 1972 Marshall Artiste 2X12 combo and when it is on form it is an amazing amp. About a year ago it developed a problem that after about 40 mins playing the bottom end just starts to dissapear. I replaced all the tubes but the problem continued and kinda forgotten about. Since plans to start playing again are afoot I need to get it working. Cleaned all switches pots etc but problem persists.
Anyone got any ideas before taking it to Bruce Millers and forking out a fortune before anyone will even take the dust cover off it?

Cheers!

Firstly, do not take it to Bruce Millers!

A capacitors gone bad by the sound of it. As the cap heats up the dielectric breaks down. Some of those caps can contain a lot of voltage even after being left off a while. Make sure you discharge them and know exactly what you're doing before tinkering.

Thanks for taking the time to answer,
Any other suggestions as to where I could get it repaired? Not up for tinkering, too many burned fingers and melted wellies to start that nonesense again!!

It doesn't sound like it would be too hard to isolate the problem. Bruce millars "might" be able to fix it, but their service is almost notorious around these boards for being terrible when it comes to amp repairs. They also charge a fortune, and considering all that needs done is a replaced capacitor (possibly), it seems a shame to spend in excess of £100, especially when you consider they'll charge whether they manage to fix it or not.

The difficulty comes when you consider posting it to someone better, it might end up costing the same price, and you have the added inconvenience of posting it.

There's a tv repair man somewhere near aberdeen i know some people have used, other than that, i think the only people i'd trust is matamp, who may or may not service/repair amps, although they did service and test mine before i got it.

You may also be able to get a repair from marshall, could be free with a warranty? it's worth sending an email.

You won't pay more than £100 pounds for that at Millers, i would reserve a guess at more like £60 to £70 max.

Ask in the forum I linked first, there are lots of members from UK who are vintage amp experts.

Filter caps have gone, I'd concur.

Send it to Marshall? Really I don't there will be a cheap option
