Modwright PH 9.0X Tube Rolling Question

Just a heads up, the Sovtek that are in the pre are really the only option. I ordered a set of 6C4 Mullard & their to small.

@danmar123 Yes Dan told me that there is only one version of the 6C45.

@danmar123 and @audiosaurusrex This is incorrect. Electro Harmonix makes a gold pin 6C45, and the another, the best one is the Russian Reflektor 6C45. They are both better than the Sovtek, with the Reflektor much, much better. That said, they are very rare nowadays and very hard to come by. That said, there is no tube equivalent to the 6C45.

I owned a 9.0 for a number of years and tried many tubes.  If you have a tube rectified power supply I would upgrade with a gz34 metal base.  It made the biggest improvement to any component I've ever owned. 

@testrun This thread is about the PH9.0, which typically doesn't have a tube rectified power supply. That said, the older SWP 9.0 did and rolling that tube led to substantial upgrades! Did you have a PH9.0 with a tube rectified power supply? I asked Dan about that years ago and he mentioned the SS and tube versions were not interchangable.
