I just got my Marshall DSL 401 in the mail.
I love this amp.
I love the tone, it works perfectly.
It doesn't get sick distortion, but with a pedal, that's not a problem.
The clean and overdirce channels are awesome.

There's one problem.
There's a standby switch.
What does this do?
In what order do I hit the switches when powering up/powering down.
I'd appreciate some help.

You turn on the power switch than the standby. The stanby allows you to keep your tubes warm, without any sound coming out. Example: if your playing a gig and you take a break between sets you turn off the standby and leave the power on to keep the tubes warm.

Thats pretty general i know. Sorry.

it also allows you to warm up the tubes without pushing them so it ruins the tubes or something like that. anyhow when powering down ive had no trouble with just hitting the power then standby or in whatever order youd like.

powering up: you turn the amp on, and standby is ON so that there is no sound coming out. you wait a minute or two, then turn standby off and then you should have sound. unless your amp works the other way..i'unno.

to turn off, i simply put the standby back on (my amp is red when completely on and yellow when in standby) and then turn off the power (if im done)

It's really a myth about "cathode stripping" in small tubes like we use in our amps. That was something that happened in big transmitting tubes with much higher voltages on them. But I still do leave the standby switch "off" until the tubes fully warm up, just in case it makes some miniscule difference in tube life, and also switch it "off" for a few seconds before turning the power off, to let the high voltage in the power supply's filter caps bleed down before cooling the cathodes. Unnecessary, but it makes me feel better. I don't worry about amps that don't have standby switches, none of the consumer electronic equipment that used tubes in the old days had them. TVs, radios, etc. The standby switch is mostly useful for silencing the amp when you want to be able to bring it back online quickly without having to wait on tube warmup. Leaving tubes with the cathodes hot but no cathode current flowing (as with the standby switch off) for prolonged periods can damage the cathodes' emission capability, a condition called "sleeping sickness." I'm not worried about that with a guitar amp, either. I've often left mine idling that way for hours (and on one occasion, inadvertently for several days) with no evident harm. But the Radiotron Designer's Handbook, 4th Edition, has a lengthy discussion of these issues and recommends powering off the equipment in most cases if it's going to be unused for over 10 minutes or so.

Careful with that explanation there!!! My standby switch has 2 settings: Standby, and ON! So obviously I wouldn't wan't mine in the ON position when powering up!!! GRRR can't they get a universal language for this stuff? Smiley

There's a manual for the DSL401 on the Marshall website. The standby switch was also explained there. It was a little confusing at first, but after the second reading I got somesort of an idea what its for.

Directly from the manual (as I said, it's a little confusing).

  • 11. Standby Switch
    This turns the high voltage feed to operate the
    valves on and off.
    *User Hint - This switch should be used for (a) allowing the amp to warm up before turning the Standby on (at least a minute - preferably 2/3 minutes if possible) and (b) turn the Standby switch off when taking a break (rather than turning off the whole amp), thereby keeping your amp at the ready, without waiting for it to
    warm up again. Remember to do these two simple rules and your valves will love you for it and should last an awful lot longer before replacement is needed.

  • 12. Power Switch
    This turns the mains electricity that feeds your amp on and off. As stated before, turn this switch on for at least a minute or two before turning the Standby on, to allow your amp to warm up.

    on your amp it really should say "power - on" and "standby off - on"

    cuz i used a TSL100 head today and thats what it said. very very easy to understand as far as i could see Smiley

    A little offtopic, but i'd like to ask, how's the amp. I'm currently thinking of getting a DSL401 myself and i'm a bit curious Smiley
    How is it for hard rock and metal (without a pedal)? Can u get good overdrive/distortion out of it?

    I am not a Marshall player, but I play tube amps exclusively (unless they all break down). And I find that after running my amp for a period of time, it gets "hot" not just the tubes are "more warmed up" but it is more responsive.
    I think leaving the power on and engaging the standby for short breaks are long warm up periods is beneficial to getting the amp to that hot-tube ready to really play stage.

    It does seem like they sound better after being on for a while. It might just be in my head. I mean like 30 minutes or something.
