This will be a performance test regarding the Schiit Saga pre-amplifier utilizing two tubes that are different.
The system and additional pipes are on loan from sort user. Look at writeup on Schiit Saga in synchronous thread.<
The stock tube is a Russian made clone of 6NS7 which goes by label of 68HC as i mentioned in the review of saga. The additional pipe supplied is from Raytheon and had been manufactured in United States Of America. You can view them side-by-side here:
The 68HC is regarding the left plus the Raytheon 6SN7 is in the right.
The pins on some oxidation was had by the 68HC on them. In comparison the pins in the Raytheon 6SN7 were pretty clean.
I didn’t duplicate the dimensions of 68HC. I recently went a number of the tests on 6SN7. Generally there be some variation in performance associated with the product general but ideally that is lost within the sound, pun intended.
Let us enter dimensions and discover if our western, genuine 6SN7 provides on its promise.
Dimensions much like the review, we began my screening by calculating performance stability that is warm-up
The most effective two lines come from Raytheon 6SN plus the bottom two with 68HC. We come across that the Raytheon pipe actually has higher distortion! We shall quantify that briefly.
Regarding the side that is positive appears to be more stable with less deviation into the graph. Not too this matters much given the tiny variants at macro degree.
Through the dimension we noticed my light that is LED was. It absolutely was about a base over the Schiit Saga. (more…)
