Hi Fishwater,
I have a pv10al that I bought new I do not recall seeing in the manual that it inverts polarity. I also own a premier 11a and it had a seperate paper the size of the manual warning of polarity inversion as well as a note in the manual. I will check to see again, but I'm sure it does not invert. I listen to a lot of types of music but I do prefer music that drives and has punch lower down. A friend lent me a pair of Mullard 12au7 tubes and that started my quest to purchase a pair. They sound a lot warmer than the standard philips tubes and seem to push the lower mids up a bit. I think this helps rock for two reasons one being that most rock tends to be poorly recorded and over prossesed and can sound harsh at best. Theese tubes are killer. Pay the extra bucks and you will I'm sure never regret the $$. Let me know what you think if you do it.
ps I have my pv10al for sale and I have a pair of tubes that are not even broken in yet as well as 3 other pairs. I have listed them all together as one pakage so if you are interested I will sell them.
Tthat is a great little pre amp and I'm not sure replacing mine is the best idea but when I get my new one (premier 14) I guess I'll know.
