The ATU on that thing uses the same forward and reflected power meters as my ST-3B.

Correct. I have a rare ST-3C ("Commercial") tuner, two of the ST-2Bs and three -3Bs...meter reuse throughout.Originally Posted by KJ6BSO
Note the "Swan" logo meter in the amplifier. Must have had a bunch left over from the 1500X.

Is the st 5 just a tuner able to handle more watts than the st 3?
The ST-5 uses a toroid inductor and edgewise meters, as opposed to the ST-3's PI-Dux coil and standard sweep meters. The aim was to shrink it to a size small enough to fit into its suitcase. Power handling...it's capable of coupling the output of an Astro D to loads of different impedances though you aren't going to run a kilowatt through one. Core saturation of the inductor is the limiting factor where applied power is concerned.

There is an ST 3B on ebay, meters sure look better than ST 5. Eham rates it high also, so they must be pretty good.
Note who wrote the most recent review. The call sign might look familiar.

Haven't checked over there - I may go add a comment.
My ONLY gripe with the ST-3 series is that the shaft couplers and fiberglass shafts used to connect the tuning knobs to the variable capacitors will occasionally loosen up and result in a bit of play, which prevents "precise" tuning adjustments. The fix is easy, though - open 'er up and gently tighten the hardware.
The ST-2B and -2R are different animals altogether, and don't have an antenna selector/tuner bypass switch. Which is one thing IMNSHO they truly need.

The call does look familiar. its the guy that VE7DCW warned me about.
