Replacing GZ34 in a JTM45. Rebias needed?

Post by Melodyman » Fri Sep 24, 2010 1:33 pm

Hi all..

Not sure about this one so I thought I'd throw it out to you experts..
Found a brand new late 60's Mullard GZ34 and want to replace the Sovtek GZ34 in my amp with this Mullard. Do I need to rebias the amp or is this a straight swap? I'm using Gold Lion KT66 and NOS Mullard/RFT preamps tubes in v1-v3.
TIA.

not really unless one of the tubes gives too low voltage
