Checking current

[MWJB]

What voltages did you get (AC @ pins 4 & 6 of recto, dc @ pins 3, 4 & 8 of 6V6s)?

The worst thing that can happen is that the amp will smoke/smell/blow a fuse (as long as you have your hands in your pockets) and you'll have to turn it off & replace the PT...which you suspect anyway...and you've had practise doing.

Get back on the horse.

Use the current limiter to fire it up for the first time if you are unsure of anything.
