I can do the tube change over if you want to go that way.
Leben CS 600 pre-amp tubes
A question regarding the Leben cs 600 pre-amp tubes, as mine are getting a bit long in the tooth. I understand the 6CS7 has become scarce ( and hoarded).
I have heard varying opinions regarding whether the pre-amp tubes need to be matched. The importer suggested not.
Has anyone replaced their 6CS7s with unmatched tubes?
Thanks
