    In the not too far future, I'm going to be working on a local connection.

    https://www.tubeboutique.com

    the guy is selling out of his house & lives a few miles from me. I travel within blocks of his house 1-2 x's week, when I go visit my Dad...

    I stumbled on the UK site a couple years back. They also had a store, w/ NOS tubes as well, but, they closed that part of the site down.

    They sell (some) SED, & NOS:

    If you click on the link here:

    it shows their tubes. They are claiming to make a Brimar copy:

    Also, speaking of Brimar, they are back in business. Currently rebranding tubes mfgr'd to their spec's, but working on making great British tubes again.

    https://brimaruk.com

    the project:

    so, they are something to keep an eye on & support in the meanwhile, if you think their endeavors are worthwhile...

    Didn’t Marty have some PM tubes he was passing around back when he was still posting here? The name is very familiar.

    I'm not sure. I know they've been discussed some. I remember Marty doing a JJ/Telefunken test & was talking about those Northern Electric (Canada) tubes, but, the NE ended up being Chinese, IIRC.

    I like the AC7HG+ in V1.

    Also the JJ 83MG is very Mullard like and CP.

    I used a 12AY7 in V1 and actually enjoyed new textures and dynamics. Others may pass and that's fine. Fun to mix the pre's.

    What PT's are in it Alan?

    I read that they are JJ’s but I didn’t pull one and look at it. The side facing out is blank. Next time I’m in there I’m gonna check and see.

    I got my caddy out and started testing tubes and checking out what I had. I found an old 1959 Matsushita long plate. If they used Mullard type codes it would be an mC1. I’ve used those before in V1 and they are really good. Found a couple of Sylvanias that test ridiculously good too. I’ll try those in V3 and V4.

    We've found some great combos. In the new DSL' s more and more I'm finding CP to do well. Course it depends on how the amp circuit reacts. The newer versions I find ANOS less friendly. Newer versions. Which money wise is cost effective. Never turn my nose at a great tube tuning though.

    I almost find the 83MG RFT like. Meaty!

    So far it seems to be responding like my old DSL50, but this is my first roll. I’m looking forward to playing around with it.

    JJ ECC83MG. Really the only one out of their ECC83 tubes I've found good in my ear. Only in V1. Meaty in the mids. And I love meaty Marshall mids.

    I agree. V1&V2 set the template.

    I have an RFT in V2 in some of my amps, no DSL. I should try the Raytheon I have a couple of those in PI slots.

    I don’t know what it is about a Raytheon black plate, but they are magic in V2, at least in the DSL. Marty used them in a lot of other Marshall amps with good results too.

    This thread is piggin' massive!

    I am sure the answer I want is in here somewhere, but there is no way I can trawl the whole thing for it!

    So, can someone please point out to a numpty where each preamp tube is in a DSL40CR.

    i.e. Looking from the back of the amp, with the back off, from left to right, which is V1, V2, V3 & V4?

    Appreciated in advance!

    V1 is farthest to the right with a shield over it. The rest follow in order to the left.
