Audio Research VT100 MKIII Tube Replacement


Hello,
I recently bought a second hand VT100 MKIII. I will replace amp's all 12 tubes. 4 pairs are 6550 I already ordered but I am confused about should I replace them with  4 single 6H30 tubes. Should I replace them with 6H30Pi or they have to be identical as 6H30.
Thanks !David.

I send my VTM200's in to AR every so many years.  They take care of everything.  Excellent service gets best performance.
