I took it into Marshall, all they found was a loose connection and replaced two preamp tubes which he said were going microphonic . Havent noticed the issue since but I’ve only had it turned up properly a couple of times. So time will tell. Thanks for the input guys

Yeah an email has been sent with an audio clip so see what they come back with. Having not gone into a local shop to buy it there’s no shop- customer relationship so I’d rather just take it over to Marshall myself. And I can have another look around the museum too :D

It’s brand new. I checked the purchase date literally had it 2 weeks. Marshall HQ is only about an hour away, but I know warranty stuff usually has to go through the retailer and the amp came from a store in Portsmouth which would be a couple of hours each way at least. They were the only place that...

That would be handy if that’s is the case gainaddict, they’re less hassle to change at least. Quite happy to re bias an amp when fitting new output valves but on a new amp I really rather not have to! That said if I have it to bits to change preamps valves I perhaps should check the bias in it. Seei...

Hi Anitoli, thanks for your advice. I take it Deoxit, is just a contact cleaner? I’ll take a look tomorrow I think, we’ve got a reversal Wednesday night so that’ll be the first chance lll get to turn it up unless the neighbours go out tomorrow. Is it worth putting contact cleaner on the tube pins an...

Hi everyone, I’ve literally had my JVM 205c about 3 weeks tops and already I seem to have a problem with it. With the master volume, either 1 or 2, at 4 or above I’m getting a horrible crackling sound. It is most prominent if I palm mute a G chord, and it’ll do it I almost any mode. The strange thin...

you're welcome dude!

Thanks gainaddict, I’ve watched some of your demo vids. Top notch playing there buddie!

Cheers

Cool, 45mV would be the same as what they stated for the old DSL 50 too and a lot of people said that was too hot in that amp too. I think I used to run that at low 40/39mV. They’re Svetlana the stock tubes? Hard to tell when they’re marshall branded. I’ll keep that in mind when it comes to retube t...

Ah great thanks for that. I was wondering if that was the case but wasn’t sure. To be honest I don’t think I’ll use it for that I’d rather use the second master volume. With the biasing. In the past it’s alway been whatever the figuer per test pin I take it is the same with the JVM. I’d be looking f...

Hi everyone, I’ve finally got myself possiblly the amp I’ve always wanted, that being one of the JVM series. My budget stretched as far as a 205c which I’m really pleased with. It’s so versatile I’m not quite sure where to start with it :bgrin I opted for a combo over stack as I’ve experienced the j...

Haha John I don't know about talented, that was pretty much the whole of my stock repertoire!! As for the master volume it was on 7 or 8 so not quite flat out but compare to how loud I can play it at home it was bloody loud. It's great to get to open it up like that. I go up to that place most weeks...

I must admit I spent many a day regretting getting rid of the first one. With it being brand new from the shop I new its history and everything, when you buy used theres always that doubt in your mind about what sort of life its had till now. I took it in to Marshall this week to get them to check o...
