Late to the Trainwreck party, gonna build one anyway.

Are the photos above clickable to view for you? I don't have a current image host to work off of.

I tried 6V6s, and they work. They do make the amp less brutally loud, but they also seem to get less overdrive and in general the sound of the amp is less focused. I don't prefer them.

Can you post the pics in a way that they can be viewed here?

Look forward to hearing your advice on the build.

I changed preamp tubes in my last express, something that made a great difference.

V1: tungsram (amazing)

v2 RFT or tungsram

v3 simens/halske long plate

Well, yes, if you are a member of the Marshall forum. Since I am registered there, I'll download them and post here for others to view.
Sharing images via link to an image hosting site (or any other site) is not ideal, as they tend to disappear eventually. Best to upload them to this forum.

Maybe I have to get a paid membership to be able to upload photos? Is that it? Because I don't see an option to upload photos here as of now.

The most obvious quirks about the way I made this:

The power board and preamp board were built with two entirely different turret styles. I changed styles midway, and decided it wasn't worth the effort
to redo the other board with the new turrets. Both get the job done.

I went with a current style Marshall impedance selector.

I went with two multisection canister caps instead of six discrete 20 and 40 uF filter caps.

Incidentally I bought 10 of the cement block power resistors. I still have 9 left if anybody wants one for a build.

Strange that I never noticed it. Never looked down toward the bottom of the page. Or maybe it has something to do with my blind spot lower in my vision range, which is always there whether I notice it or not.
