I can certainly still do the mods to a 5150 no problem. The 2.5 to 2 channel conversion is a bit different between a 5150 and a 5150 II. I can also recap an older one if desired. Note the pentode conversion involves cutting traces and basically turns a 6505 into a 6534. I was doing this well before the 6534 existed.

Considering everything is made in China now that doesn’t surprise me at all. Older made in USA models made before the release of the 6534 and original 5150 series don’t however. You can convert any 5150 to run pentode. With tube quality today the power tubes will last longer with the lower screen grid voltages in pentode.
So I’ve never messed with a 6534.. know nothing about them. I’ll have to look into some shootout videos to get a grasp of what their tone is like.. I’m trying to track down another 5150 & will be reaching out when that time comes

Best way to describe this mod is that it’s if a Marshall and a 5150 were mixed. It’s closer to a 5 gain stage Marshall afterwards except more rowdy and hefty due to the 5150 circuit design stemming from a SLO.

Thanks man! That sounded gnarly… 3/4 of my amps are EL34s so this would be right up my alley.. No doubt it sounds like a great blend between the two! You guys are sending me down another rabbit hole

That is a cool concept! Hernia waiting to happen if I tried loading that into my truck, but I like the extent this man went to so he can clean up his stereo rig. Very efficient if you are loading into a trailer.
Typically tubes are chosen to compensate for the cold bias these days. If you didn’t retube it at the same time to a colder tube it probably did sound off. Just food for thought.
