Bolero - I can't say for certain why one tube costs more than another except for the usual: supply and demand. IMO it has more to do with performance in the targeted amp. In this hobby subjectivity is king. The beauty of this amp is the flexibility an owner has in trying out 'many' different tubes! Each tube characterized by its own signature sound. Check with Leben (muson@leto.eonet.ne.jp) about mixing different brand tubes within the CS-600. Since this amp is auto-biasing you may be alright. I always put in a matched quad just to be safe and have never 'mixed' different brand tubes in the CS-600 WRT the power tubes. Most probably would not. See the linked sheet for possible power tube combinations sent to me from Yoshi Hontani (Managing Director): CS-600 TUBE COMPATIBILITY LIST Sounds likes you've only had the KT77's in the CS-600? What other's - if any - have you tried and/or compared them to in the amp? If you haven't started your "rolling" (tubes) adventure then buckle up and get ready for the ride of your life. enjoy the music... |
EL34 and 6l6GCs have pretty different sound signatures so it will be different as EL34 have a lot more warmer lusher sound (Generalising) and 6L6GCs much more bolder and wider across the range (Again Generalising) for the price the Russian 6l6GC reflector equivalents (6n3c e) are great..they are not expensive and definitely better than the SED6l6GC i used in the past. But for me..as has been mentioned by Notec, the KT120s are in a different league altogether . the 6cS7s, at least to me do have an impact but its minuscule in comparison and in my opinion, need be on ones agenda only after changing the power tubes. |
