Hi guys,

Someone ask me to build a 1974X with one 12 and a 1973X with two 12's. Any difference in the two schematics?

Thanks,

Billy

Can't say about those new reissue "X" amps. I just posted the original schematic for you a few days ago.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

It's in your other Marshall 18 watt thread.
