First Sound Preamp Owner's - What NOS tubes?????


Of those that own First Sound Presence preamps, what NOS tubes are you using in your unit? What sonic character does the tube(s) yield?

Thanks, from another new First Sound owner.

Philips SQ E188CC. These add a little warmth to the FS which it needs. I prefer even a little more bloom than the FS can give.

Anyone have a good source for Mullard tubes? Looking for a pair of Mullard E188CC tubes.

The MIT PPFX capacitors are contributing to the lack of sweetness and bloom. I would change those caps, otherwise IMO sell the pre-amp.
