Marshall Park series won't make any sound!

I don't quite understand how this site works, but I saw you were able to help someone with a similar problem to the one I'm having and wondered whether you had any advice...

I bought an 80 watt Marshall Park series combo amp second hand a coupleof years ago. When I turned it on the lights came on, but it wouldn'tactually produce any sound through the speaker. I found that if I keptit on for long enough eventually it would produce sound. This problemhas been going on a while, but I have another amp that I use for gigs,so it didn't bother me that I had to wait for it to work. However, I dolike to practice at home and very recently it doesn't turn on even ifyou leave it for hours!

I was wondering whether you knew why this might have happened or have any recommendations for how to solve it!

Many Thanks
Ben

    Thanks anyway.

    I'm sorry I'm not really sure what you mean. I don't know much about technical terms. Can you put it in idiots terms?

    Thanks

    I've never heard of it taking THAT long, but if it's a tube amp, it has a warm up period (If you're gigging, I bet you know this already.)


    Maybe you've got a bad tube or something.  Beyond this, I don't know.  Good luck with it.

I have a marshall mg250dfx amp & have just got a marshall mg programmable footswitch for it model number is pedl-90008 but when plug it in nothing happens is this pedal compatable with my amp/


According to the Marshall site, the PEDL-90008 is not compatible with your amp. Only the 2-way foot controller that came with the MG250DFX is compatible with it; that foot controller is the PEDL-90004. See http://www.marshallamps.com/product.asp?productCode=MG250DFX&pageType=SPECS . If you need to replace the foot controller, it appears to be available at several vendors. Musician's friend is one online store with it in stock, http://www.musiciansfriend.com/amplifiers-effects/marshall-footswitch-for-mgdfx-amps .

The PEDL-90008 is compatible with amps in the MGFX line listed here: http://www.marshallamps.com/product.asp?productId=174 . The second column is for the PEDL-90008.

I wish that I had better news for you.

My Marshall mg100dfx has just recently began to schreech and buzz as soon as I power it on. No instrument plugged in. No previous buzzing or unusual sounds. Now all of a sudden when I hit the power switch...


It sounds like a bad capacitor in the item, the value changes as it warms up. I would suggest pre-warm up before the public arrives because this may take time to find the problem, and then you can tackle it or bring it to a technician.

Opening the speaker box, Peavey KB 60 Amp


Hi...

A couple of top screws and some on the back lip of the chassis . The amp slides out but be careful not to pop the speaker leads I own a KB50 and have worked on other KB amps.

Sounds like you need a new reverb spring set.

Peavey is very good for parts

Guitar amplifier


Hi thecross

I have fixed so many of these amps over the years... Marshall Valvestate series of amps are notorious for dry solder joints developing on the main PCB. If you have the skills(or an old mate that does)Remove the PCB from the chassis and resolder any suspect dry joints and you will fix the problem. Check particularly about any components there the PB has changed colour. This is an indication of heat in that area, and heating and cooling is a major cause dry joints.
I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

Marshall 8080 valvestate amplifier


There could be a short in the rectifier diodes or in the transformer itself. Can you take some measurements inside the unit?

Let me know.

Marshall valvestate 8040 - how to change the valve?


Hi chagzuki, you are right, but only when the valves are used as outputs, You amp has transistorised outputs, and a single tube used for distortion/gain. You will get a very long life out of this tube also because its supply voltage that is is used in the valvestate preamps is really quite low. Just enough for it to work really, so the tubes life can be expected to be much longer than normal. It is also a preamp tube, not an output tube, so they rarely need changing. If you ever did want to change it(dont bother), it is located on the PCB inside the unit. You have to slide the sleeve off to get at it. Get yourself a JCM800=the best guitar amp ever built(imho), then yo got pure Marshall tone, and output tubes that need changing every 6 months or so. Now go RIFF OUT and dont worry about your valvestates' "valve"
