"Hi Fidelity" aside (No offense to the 14.178 mHz group), the 6AK6 appears to be an industrial type equivalent to a PM95. It does have the same pin-out as the 6AU6 and similar ratings. It just might work.
However, Drakes have their own audio quality and are designed around the concept communicating effectively...Not for the listening to the rounded wonderful tones of your favorite announcer or listening to your favorite classical piece. The change to the 6AK6 will not resolve the audio quality resulting from the design circuit.
Tubes such as the 6BA6 and 6CB6 would be worth a try. The 6BA6 may give better signal-noise characteristics. In the receiver, this would promise better performance as would the 6CB6.
All three tubes are in the same price range. If you want to blow-off some money, why not try all three?

I have bought tubes a few time from Electron Tube Enterprises. One time Dick sent the wrong tubes, but it was easy to get that straightened out.
His prices are good.
