The output transformer has a 16 Ohm tap. I have never heard of a 16 Ohm output 5F1 but since I have this nice 16 Ohm speaker I would like to wire up mine this way.
The question is will it work without damaging anything and will it have any effect on volume and or tone?

Do you have an original 5F1 Fender amp or did you wire it yourself?

The output transformer "needs" to have a 16 ohm tap-- at least for it to work as originally designed. I think original Fenders had a 4 ohm (sometimes 3.2 ohm) tap only, which is too far off for this to be a good idea.

Many modern kits have 8 ohm taps on their transformers, if you have one and use it, that would be safe. Power will be reduced, and tone will be different-- not necessarily worse, just different.

Few modern kits have 16 ohm taps but if you assembled your own with something like a Hammond 125 series transformer, they can be configured for 16 ohm output. It can be a bit tricky but Hammond has diagrams describing it.

I have a classic tone opt with gray wire identified as 16 Ohm tap. So I am set as far as the output transformer goes. It's just that I have never heard of 16 Ohm tap being used on a 5F1 so am wondering if there is some problem with using the16 Ohm tap.

Nope, no problem. You just don't see it a lot because these amps used 4 ohms originally and 8 ohms seems most common now, so the designs assume you'll use one of those.
