Shootout of Nos 6sn7 tubes
They are gently used. Thus no burn is needed. It has nice body and full decay and the widest soundstage that I have had in my room. It is worth every penny. There are some USSR dealers in Ebay who sells tube with 1578 logo with 60 day’s return. But it will take 6 weeks to get them. I may need to order some more from Russia for Freya which use quad 6sn7. |
Damn it, shkong78- Why didn’t you do this shootout, and test those Russkie tubes, a month ago? I’d have been looking for a pair of those, instead of buying the T-S’s. Now, I have to start shopping again. Thanks, pal! ps: What’s that seller’s eBay moniker? |
If I had 1578 in the shootout 3 weeks ago, then i would not have bought more Kenrad vt231( Now I have three pairs they are pretty good for the money). But I could not get 1578 at the time. I heard that there are difference between 1578 made in 1970’s and 1980’s. The one that I got today was made in 1980’s. Next week I will get tubes made in 1973. I will do comparison between them. It seems that there are good Russian dealers in Ebay. I will also do more study about it since I need more 1578 for LM508 and Freya+. Thomas |
Since I use pair of 6sn7 in LM508 and quad 6sn7 in Freya, i consider ordering more 1578 tubes. Just out of curiosity, i also had ordered cheap 6n8s tubes for comparison. https://www.ebay.com/itm/QUAD-FOUR-Matched-Balanced-Russian-6N8S-6SN7-double-triode-TUBE-NEW-NOS/312402083888?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 I do not expect them to be as good as 1578. |
