Looks good to me.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

Hola amigo !


No issue if done right. Even if it would be your first amp ever. Many pros here to help you. Just be aware that the amp won't have the same tone due to Voltage and OT specs diferences.
You'll have to use a 4 diodes bridge to get your ground reference or more easy a bridge recto all in one with 4 legs comin out of rhe bridge unit.But I guess yoy k now all that.


Good luck and have fun
