Deluxe Reverb copy Rectifier Screw up

[TerryD]

I have a real nice Deluxe Reverb Copy called the Stinger "Texas Tornado".  In any case I must have been swapping tubes and got a 5Y3 rectifier stuck in there.  I didn't use the amp much because it sounded- distorted -like crap.  I'll have to get the GZ34 back in there.
What should I do to make sure everything is Okay?
Would there be any advantage of putting a 5U4 rectifier in?  If so what would I need to do to make it right?
 
Thanks, Terry

Plug in the correct rectifier. Play the amp. 

There was probably no harm. If there was damage, the rectifier would've died first. That would probably have shorted plate to cathode, which would have popped your fuse (there's a chance this scenario could damage a filter cap, but the fuse would probably die in time).

You hadn't mentioned any of that, so there was probably no ill-effect from the 5Y3.

The PT for that amp probable doesn't have the extra heater current for a 5U4.

5U4 needs 3A heater current, GZ34, 5V4 and 5Y3 only need 2A heater current.

No big deal at all. If I'm fixing an amp with a GZ34 rectifier, I generally throw a 5Y3 in there during the repairs. Basing wise, they are interchangeable for all practical purposes. I have loads of 5Y3s, some of them pretty old (WW2 vintage) and I would much rather blow up a 5Y3 than a GZ34. A 5Y3 should also reduce the B+ by say 25 volts or so during checkout.
