I have a Marshall valvestate 2000 AVT100 and suddenly the fx module stoped. The amplifier works like always "good" but the fx module is death. What can be the matter??
It doesn't works,
Simply, I wish to put some 6550's in my JCM800 2203. Is there any possibilty of achieving this, if so How?
My JVM 410C doesnt have any volume coming from the channels.
One switch works green yelow, not red. Works fine with switch two. Switch three works green and yellow, not red.
switch four doesn't work at all.
No sound out of these channels without footswitch. Same results. Now, making a poping noise when turned off. I just got htis amp in June. Played a few weeks and then boom, nothing.
I tried using the FX Loop in back. That's when this whole thing started. As I correctly plugged in as instructions say, it immediately didn't make sound in these channels. Unplugged, guitar going straight in, same stuff. No volume through these channels.
The tubes are red, all glowing.
I need help. Thanks.
Just purchased this amp. I am a little suprised at how hot the metal faceplate on the control panel gets during use. I know tubes generate heat and the DSL40 has the four pre-amp tubes just behing that faceplate. Still, just wondering if this is "normal". This is occurring even in low power mode, at relatively low volumes (set at 2 or below) and the Ultra Gain at about three quarters.
What the stock original preamp tubes of this head?
Hi, I've just bought a DSL5C combo that sounds fabulous.
Just to know when I will have to make tubes replacement, can you tell me:
My JCM 900 doesn't sound the same as it use to, had a local tech. put in a new transformer and tubes but, no balls. How do you find a trained Marshall service rep. in the states?
so what series is the vavlestate 10 and valvestate 40V? can't find them in the manuals section
Hello ,,, being new to this site and Marshall amps hope I don't sound to dumb... Can I go out of the line out on my valvestate 10 and into the input on my valvestate 40V?
HI just got a new (3 days old) JVM 205C and played it a couple of times then when I went to turn it on again it will not make a sound!
It starts and all the tubes light up but when you turn off the standby nothing happens and no sound at all comes out, not a click as if the standby swith is doing nothing.
I did read the manual about the FX loop button muting the amp without effects plugged in but I have tried everything I can think of so far, guitars, leads other power sockets but no go!
Anybody have any ideas???
can you recomend a new set of vaves for my c5 01? also, do i need to have the amp biased when changing the el84? thanks.
Hi, to change the power valves of my JVM 410, do I need a matched quartet or I can use two matched pairs? The bias is set by two separate trimmers, one for every pair, so maybe two matched pairs will be enough?
