Can anyone identify the secondary voltages for this power transformer.
It reads 89108 606-551.
It was pulled from an old console but I found references of it used in the 40W 1966 Fender Reverb Deluxe amplifier as well. It has only a single HT secondary winding.
Much thanks.

Rather than asking, measure it 😉
Besides, I very much doubt that something "pulled out of an old console" is the same as "something used to power a Fender amplifier" , not the least reason being that Fender always used OEM custom made transformers, not a generic one bought over the counter.

So many ways...
First, Fender Deluxe Reverb amps are tube amps, and any power transformer in one would have both high voltage center tapped windings, but also a 6v heater winding, and a 5v winding for the rectifier tube. Not to mention a bias supply tap.
Deluxe Reverbs were based on a pair of 6V6 tubes, and none of them put out 40 watts.
Fender transformers of that era did not have part numbers in the 8xxxx range, they would be in the 22xxx range.
As Juan said, Fender had their own transformers made, with their own part numbers on them. No other company would have transformers with Fender numbers on them.

And all the 606-551 indicates is that it's a Schumacher(606) built the 51st week(last two digits) of either 1955 or 1965(middle digit) most likely 1965 since it supposedly was from a 1966 amp and as everyone stated above, not a Deluxe Reverb. The 89108 is likely an OEM number for whoever Schumacher made it for, so the numbers mean nothing in regards to output voltages(at least to us). We can't tell from these numbers anyway.
Separate the leads and tape them down to the work bench separated by a couple of inches. It likely has two blacks which would be the primary. Ohm these out first to see if they have continuity, or is shorted. Then apply voltage, preferably with a variac if you have one and bring it up slowly. Measure the other leads(secondary). I have found that at about 100-105 volts on the primary, if it's rated for 120v, it will give you close to what the full load secondary voltages will be. The off load voltages will be quite a bit higher than when fully loaded.

^^^^^^^ loved this method.
As of the great detective work shown above, now I understand why somebody would (improperly) think it related to a '66 FDR .
Yes, Schumacher was a Fender supplier , so in a very broad sense somebody could say "those were the transformers used by Fender" , but only speaking of the brand, nothing deeper.
Like saying "Drake? (or Dagnall) .... oh, those were used by Marshall .... "
Truth is that all those important OEM companies had many customers or they would have failed long ago.
Thanks! I should have specified that the relation to Fender was just something I came across based on the numbers on the transformer alone. I am aware there are no filament taps on the secondary. It's a moot point as I found a more suitable transformer for what I was looking to do.
I don't have a variac which is why I hadn't fired this thing up yet. I labeled the leads and do have bucked 105V/115V available.
