System too harsh Help

Sansui80 - I have a Ref 2.2 (not Linear, but original) on which QFS did the "factory" upgrade. I am very pleased with the improvements - improved mid-range, smoother, more detailed yet less harsh. However, I've been told that QFS is no longer the U.S. distributor. I've also been told that the mod on the Ref 2.2 (replace output caps to 2.2 450 volt Auricaps precision caps, replace output diode, re-wire power supply for voltage to caps, replace output tube with JJ Tesla EC-99) is not really a good idea since tubes like the JJ Tesla EC-99 are not meant to be installed on their side, which is how the mod is done. I e-mailed Stephen Monte at QFS for clarification on this but got no response. So while I would highly recommend Stephen's mods for improved performance, I would be concerned about their application to the player. I have NEVER had any trouble with mine since (2 years now) but would be cautious since Stephen has not answered my conerns.

Sansui80 - I am not recommending you not do the mods. I am only suggesting you speak with Stephen about this issue and only proceed if you are satisfied with his explanation. All of my dealings (general questions, work done on my amp and CDP) with Stephen up to this most recent issue were great. Please let us know what you find out from him and what you decide to do.

No issue whatsoever horizontal mounting of ECC99 in Ref 2.2! None! I have it on good authority (well known and highly respected tube guru) that there is NOT any issue mounting this specific tube (nor ANY tube unless restriction stated in its data sheet) horizontally. Been a couple of years for this thread but must set the record straight. This fear has plagued the back of my mind for years. And it was pure hogwash. So fear not.
