Stock Marshall Tube Codes

[Headache]

Just adding some data

My 2016 DSL 100 had these in it.


Can't find info for the red labeled 90067, but it's really close to the 00067 JJ low microphonic?
Looks like the same exact build and components....

Marshall, at some point recently, started putting JJ in V1 & Shuguang in the rest of the ECC83 slots. The JJ is the most quiet, so they use that in the 1st slot. The rest, the Chinese are good enough & are more aggressive...

 

[Headache]

Mine was actually very microphonic, I put a matched quad of high gain EHX in there, after trying a new Mullard in V1.

It's purrrfect now.

current production (CP) tubes can be hit/miss...

Could be that the tube was damaged in shipping. ...

 

[Parkerx02]

What about white label vlve-00035-t and black label vlve-00008r?

Hey guys, new to site in name, been stalking you guys since I finally got a Marshall.. its a 2020 DSL20cr swapped out 70/80 for 65 watt Creamback. Also swapped the 12ax7 in v2 to a 5751 to tame the fuzz. Also played with PI and tried a few different 12ax7 and a 12at7.. the gold label 12ax7 that was in there sounds best (to my ears at least)... probably why it was in there to begin with. The speaker is breaking in and starting to sound good..

I know this is an old thread, but it's got great info, anybody know what a red label EL34 vlve-90105? from this 2020 DSL20CR.

I am pretty sure V1 and V2 were JJ's *I think* red label vlve-90066, (which I assumed were just newer red label vlve-00066, but if I am wrong, please let me know!) and the PI was the gold label vlve-00049. Shugaung high microphony.. any help would be appreciated.

I just answered someone else on this. the 000105, is a JJ, there's a JJ logo on the base.

[Robert Brussow]

thanks. sorry i read through this thread and didn't see that. Plus, I haven't taken the power tubes off yet so I haven't been able to inspect them.

maybe the mods like to make this a sticky?

these are the codes printed on stock marshall tubes with a description what brand or type they actually are... the list is not entirely complete, but covers a lot of the actual tubes being used by uncle jim today

Has anyone got an update to the code list? Seems to be a few missing now. What’s this gold label ecc83 vlve-90095 I see for sale in places for example?

I found the VLVE-90095 on a Hungarian website described as a Hand Selected, JJ ECC83

Cheers. I was hoping they were shuguang 12ax7 since they’re getting harder to find now, but it’s good to know.

That is odd, the structure, even with the short plates, don't look like JJ's. Looks more like a Chinese tube like this 7025 WA TAD HIGHGRADE Premium Selected (tubeampdoctor.com)
