    DSL40CR- Help dialing the amp in - Tone questions

    I wonder if the "stressing the power section" idea is right for DLS40CR. For example - on a clean channel, even with max channel volume the sound is still clean. The power section is not clipping it at all. According to this explanation...

    Copied that riff from Robert Baker Yutube channel. EZdrummer is pretty good :)

    Show Me Your Riffs

    I started learning this riff from scratch 4 hours ago, never played this before :) It will take months to master it as I cannot make "circle" picking movement for now... DSL 40CR ultra green channel.

    The Official Marshall Dsl40cr Information Thread

    Grab a 12AY7 too for even more options. I think the 12AU7 (ECC82) which is actually half of the ECC 823 may be to weak with its gain=17.

    The Official Marshall Dsl40cr Information Thread

    I got my 5751 and 12AT7 preamp tubes few hours ago... and just finished playing :) 1. 5751 into V1 - not much difference in gain, bearly noticeable. 2. 12AT7 into V1 - more difference in gain but not what I was after. I liked the tone anyway. 3. 12AT7 into V1 and 5751 into V2 - there it is...

    Yes. It did exactly nothing. Here is a picture: IMG_20200516_123328_1 by calzone posted Jun 16, 2020 at 7:08 AM

    5751 for DSL40CR headroom?

    @SnickSound I see what you mean. The C74 cap (why it's marked NF with no value?) kinda "bleeds" higher frequencies into distortion tube V1B with no respect to gain VR3:1 potentiometer. I don't mind that. Also, I don't need more distortion. It's just to much utra-low spectrum which causes the mud...

    Marshall DSL40CR or 20CR + Questions

    Also take into account this, its Fletcher Munson Curves: Our own devices (human ears) are at lower sound levels less sensitive to mid frequencies. We may think the mids are lost somewhere else ;)

    5751 for DSL40CR headroom?

    After playing with the Cathode Bypass Capacitor Calculator I realized that simple changing the bypass cap value results in a left-right shift of a freq curve. I'd rather have lowest frequencies attenuated, not losing low-mid range which is essential for a guitar. So instead of playing with a cap...

    5751 for DSL40CR headroom?

    I just used a Cathode Bypass Capacitor Calculator: https://www.ampbooks.com/mobile/amplifier-calculators/cathode-capacitor/ Here are results with values of actual components in V1B circuit (R96=1.8k, R97=100k, R94=1M, C69=680n): Response by calzone posted Jun 14, 2020 at 1:49 PM The second curve...

    New Dsl20hr, And A Problem...

    Thankyou @Sixstring63. I already returned DSL20CR and got DSL40CR. This one has no noise issues, still there is some room for improvements :)

    5751 for DSL40CR headroom?

    Hello, I'm glad I found this thread :) My problem is that in red ultragain channel at around 5-6 gain the sound becomes heavily overcompressed. The initial pick attack (or palm muting - even more) causes volume dip-out. I already ordered 5751 and 12AT7 for experiments with swapping V1/V2 tubes...

    Hello

    Hi, I'm a new Marshall owner, used to have some valvestate model 30 yrs ago, sold it. My Ibanez 540SLTD stayed luckily with me. Recently decided to buy a tube amp, just for fun. After reading this forum first I got DSL20CR (which turned to be faulty) then DSL40CR. The original speaker changed to...

    Yet another DSL20CR hiss thread

    I returned it. They checked the noise and said it's "normal". Whatever, I grabbed DSL40CR and... it's simply quiet. Maybe because it has master volumes :)
