If I understand you, subbing a 12au7 in V4 would limit the power output???
Meantime it sounds really good just not as loud as I expected. I haven't owned it long. Replacing the original 30 year old tubes seemed a reasonable proposition. It would be a three day affair to get a tech on it in between the driving. Courier service is more risk than warranted. If I knew of a truly worthy tube tech to take it to I could plan vacation around it. Mesa NZ told me to play it until it acts up.
