I guess with the 5691 having twice the filament current, it would need an appropriate power supply to ensure correct operation.

Yep and my croft pre had to be modded to accept the 5691, it changed the sonic signature markedly.

Did the sonic signature revert to original when you switched the 5691s back out?

Nope. The modification truly brought out the 5691's capability. So it wasn't a backwards step. It was initially quite difficult to assess what had changed and then within about 30 minutes I'd realised that the timbral quality was just on another level. Notes on things like the double bass had so much more resonance, soundstage was a little deeper with better coherence. Subtle but a big leap forward!

Ahhh, I get ya. That’s good then.
I am impressed with the 5691s, very musically satisfying.
