I will tell you another option and to me this is the overall best thing anyone can do but there may be limitations..The 6CG7/6FQ7 is the same electrical parameter as a 12au7 especially if they are using 6.3v filaments on 4,5,and 9 of your 12au7..You do have to make a change but being the 6fq7/6fq7 is so much better IMHO that I did it on every one of my mac amps with superb results.
The 5814 or RCA 12au7 black plate RCA or tele 12au7 would be the best of the 12au7s but if you have a little ingenuity you wouldnt regret changing it over to a 6cg7/6fq7.
