Phoenix Eagle Versions?

If it’s an "Eagle", it’s 25W by definition. If it’s 15W, it was called a "Falcon". Also, Bill Carlin is easy to reach by email, and he will give you the definitive answers.  Now maybe there were early versions of Eagle that could produce only 15W, which is why I suggest you seek confirmation from Bill Carlin, still found at Phoenix Engineering, last time I looked.

Haven’t talked to Bill but I found out from a long time user: The Falcon was 5W and the Eagle 15W. Later, 25W Eagles were made and I was incorrect that they say 15W on the PSU. Apparently really rare. At least I know what mine is now....

Yes, you are right that the falcon was 5 W not 15W. My bad, and thank you for correcting me. It was actually bugging me in the back of my mind that the falcon was 5 W, but I let it slide.

Those old idler drive motors as found in the Garrard and the Lenco are very in efficient, and I would not try to drive the Lenco motor anyway with anything less than the 25 W of the final version of the eagle. I don’t even think the Garrard motor can be used with one of these devices because it is an induction type motor, but I can always be wrong. I wouldn’t think any longer of driving the Lenco with out my 25W Eagle and Roadrunner.

The original Eagle used a class AB output amp and was rated for 15W max.  The wall adapter was 48VDC and 60W. 

Starting at SN 620240 the output amp was changed to a class D type and the output was rated for 25W.  The wall adapter was 24VDC and 60W.

Operationally, they are the same.
