You are "wasting" a triode by using them in parallel.
Build a conventional, 2 triode preamp and you will have *a lot* of gain.
Check the Marshall 18W, or similar amps.

I would yes recommend a isolation transformer (not absolutely needed though)
Sorry Jack, ground the chassis then plug the cord in so the active is on the chassis (e.g. a transposed outlet) and you'll blow the mains circuit protection, or maybe start a fire. Encounter an outlet which is both transposed and has an open earth (not unknown, and particularly at venues) and you're dead.
As a tech with over fifty years experience I flatly reject your advice as dangerous - an isolation transformer is absolutely needed to safely operate this amplifier, otherwise a guitarists is quite literally taking their life in their hands every time they touch their guitar.
So called "universal" appliances of this sort are abominations that should never have been built or sold in the first place, and in many parts of the world are now rightly illegal. Adding an isolation transformer will not alter the tone in any way and will make the amp what it should always have been.
