My MK III will never see a $100+ tube not even $30/Tube............
The most i spend for my CHATHAM 6AS7G's are $20/tube and some that i got from auctions it works out to $10.50/tube i've got seven tubes from that auction.
Not even the CRACK or the S.E.X. will see that amount for a tube.
My C3g adapters arrived today:
Wow, they sound beautiful with the 1578s! Too early for a full review, but I have no doubt this combination could be an 'end game' for many. Full rich sound, with great bass and not much compromise in other areas.
Hi,
After listening to the Sylvania 7963 sub miniature tube I have come to the conclusion that it needs some 70 hours of burn in to bring out the full potential. At that stage the bass became much more articulated and stronger. Tried it with my pair of Chatham 6080 tubes (nothing untoward happened) but somehow there was too much bass and it sounded boomy. The synergy wasn't there.
With the pair of RCA 6SN7GTB (top heater wire) the synergy is there, and I can revel in the clarity and detail of the entire musical spectrum + great musicality and sound stage. There is a multilayered presentation of the music, and on obscure 20s recordings i can follow and pick out individual instruments with much greater ease than before. It is hard to tear yourself away from the listening - it is so beautiful with superb sound in all ranges.
In addition, these tubes are easy to drive for the MKIII and no external power supplies are needed. Don't know what the "cryo treatment" my fans add, but the amp is literally cold to touch, and the power tubes are barely warm.
Happy tube rolling! (BTW, the entire tube complement cost me less than $20)
.......But there are some tubes that are more difficult to get a bargain on. It is very unlikely you will ever get real 1578s on the cheap.... Or Tung Sol BGRPs.
Out of interest, what differences do you find between your 7963s and the 5687s?
