RE: 12AU7 voltage amplifier

Thanks Ralph,

I thought it might not be the trim pot.

I just changed all the !2at7s to Pvanes from china and this is a good excuse to do the same for the 12au7s. Really like these high quality chinese tubes; hopefully the 12au7s will be as well matched and quiet as the 12at7s
