Hi,

I have a Marshall 9200 poweramp (Dual mono-bloc) that I am having problems with. Channel A works fine, but when I turn on Channel B, I get no output, but rather I get this low pitched buzzing sound that becomes louder and louder. (Both channels work independently of each other, as in Channel A runs 4 6L6GC tubes and Channel B runs another 4 tubes)

Also, Channel B's tubes glow blue when it is turned on. (I never turn Channel B longer than 30 seconds after that buzzing sound starts) I was wondering whether it was a blown tube or whether it is something more sinister at work, i.e. a blown transformer.

FYI, the amp doesn't trip the fuse, but rather the tubes just immediately glow blue, like the gas in the tubes is on fire or something.

Thanks for your help guys.

Hi,

 

Have a few questions about attenuator usage with SC20H amp.

 

1. Do I need two attenuators? My cabinet has two speakers (8 Ohm each), and SC20H has two separate outputs for each speaker, so does it mean I have to buy two attenuators, one for each speaker? I didn't manage to find SC20H schematics, so I'm not sure if those two amp outputs are connected in parallel internally, and I can just use one attenuator.

2. Do I need attenuator(s) at all? I want to run the amp with overdriven tubes, thus I have to set max level, right? Consultant at my local store told me it's enough to reduce "Master" volume, and EL34 will still be overdriven, if I set "Pre-amp" volume to max. But folks at Marshall forum say that it's still better to use attenuator, even in 5W mode. Again, I don't have SC20H schematic, so it's hard to tell who is right.

3. What if my cabinet only have one 4 Ohm input (2 x 8 Ohm speakers inside)? Is it enough to connect it to the amp with only one cable? Or I have to rework my cabinet to have two different inputs (separate input for each speaker)?

 

Thanks!

Ok Marshall we bought your product thinking it would be a good product. With trusted support.  You have failed your customers and your products with no support for the code amps that your customers bought. And now most are stuck with a half working amp that they can't sell or not happy with.  When will you get off your butts and fix the amps with a firmware update? And support the product and the consumers?  Let us know so we can either stick it out or move on to another product.

My Valvestate VS65R only puts out about 5% of its original wattage. It gave a pop noise a while back while I was playing  at 70% volume and fell silent while I was testing a new capacitor. I found a set of circuit boards and transformer, installed them with a new tube but only get the small amount of sound even with everything turned up. I tested it with different combinations, transformers, boards, tubes, speakers, guitars, cables, but no luck. Any help on what the cause could be, or how to troubleshoot would be greatly appreciated. Peace and Rock On!

Hello,

 

Where I can buy the Marshall Dsl40c's fuses?

I've had a hard time finding them. My Marshall went silent and I replaced all the tubes.

Running out of ideas.

 

thanks

Hi,

I just bought a Marshall Code 50, it is new but I think it have a problem.

When I move command buttons (Gain, Bass, Middle & Volume) nothing happend.

When I move Trebble button it change Trebble and Volume in the same time.

Also, I saw that settings change without touch buttons when I'm playing guitare.

I tried to reinstall the firmware but it didn't fixed the issue.

Hi,

Just bought a DSL100HR head and noticed that it is self switching from clasic gain to ultragain chanel in a random way.

It happend  3 times in aprox. 20 hours of functioning and 2 times I was not even playing the guitar, the amp was on on classic gain crunch and switched suddenly on the ultragain.

I do not use the PEDL-90012 foot switch, I use instead a midi connection from loop controller Harley Benton FXL8 Pro ( everything works as expected here , could program and switching works fine through midi). The amp works perfect in rest nothing to complain except this strange behavior.

Q:  any idea what is the problem and if/how can be fixed, is it something common ? 

Thanks in advance!

Hi,

I got my DSL 20 CR in May 2020 so 6 months ago and recently have noticed that the light underneath the power switch is flickering.

It is now significantly dimmer and a bit annoying not really what you would expect with the quality of a marshall.

Not sure if this is covered by the warranty or if I need to fix it myself.

Any Help greatly appreciated,

Thanks

Having constant issues trying to connect iPad to Code25 via Bluetooth. Sometimes it works , sometimes it doesn't.No consistent behavior.  Yes I have made sure Code25 is latest version, yes I have updated IPad. Yes I have turned it off and on again (iPad and Code). I have not hit it with a hammer YET...Settings in Ipad says connected, Menu in Gateway App says not connected.  Do search in Menu > Code is found> tap Code ID and says its connecting , Just a whirling  wheel. Meanwhile IPad settings states connected. Extremely frustrated. Is there a solution to this or did I just get conned into buying something that doesn't do what it was sold to do. Help please............

I've recently purchased CODE 25, installed Marshall Gateway, and paired the code 25 with my smartphone (Xiaomi Redmi Note 8 Pro, MIUI 12, Android 10).

All was fine, I've listened to some pre-sets using the application and tried to disconnect the CODE 25 from the phone. I've opened the Bluetooth settings on my phone, tapped to the CODE 25 device, and pressed to the "unpair" option.

BUT the CODE 25 still tries to pair with my phone every time, when the Bluetooth is on.

I've tried to reset the CODE 25 to the Factory settings, tried to update the firmware - no result. 

Not even resetting the Bluetooth settings on my phone helped to solve the problem: the CODE 25 spams my phone with the requests of pairing every time I turn the device on.
When I pressing the Cancel button on the pairing request, the next request comes within several seconds.

It's really annoying!


How to force the CODE 25 to stop spamming my phone?
