GEC 6SN7 on ebay...!!!
Rare Pair of New GEC B65 / 6SN7GT Valve Tubes in Box - eBay (item 180469649630 end time Feb-21-10 18:54:23 PST)
Well, first impressions of my TS 7236s...
More power, that's for sure. I have to back down a few notches on the volume from my normal position. It's akin to going balanced.
I'm hearing more air in my songs; the soundstage is a bit larger. Bass is hitting harder but very tight. Midrange is emphasized and highs are very extended, wayyy into the stratosphere with no harshness at all. Sibilance is tamed, it doesn't seem as drawn-out and emphasized. I've removed the EQ for the time being. Very musical sounding, it almost sounds faster but it also lets you really hear the music at the same time. These are my #1 power tubes and I see no need to ever change them. I need to stock up on these babies.
I'm now able to listen to the remix of Pearl Jam's Black at high volumes without knives in my ears!
This is a great combo: TS 7236, TS 6F8G, EML 5U4G. My only complaint is a buzzing, just when no music is playing. I first got the buzzing back when I put in my TS 6F8Gs, so today I'll roll my NU 6F8G RPs and see what happens.
Just put in my NU 6F8Gs. The sound is pretty much the same, but it's a bit smoother. More midrange and slightly more detail than the TS 6F8Gs. No harshness at all. Bass is still deep and tight. The buzzing I talked about earlier occurs at a higher volume.
I noticed that the tube I have on the right channel picks up any vibration incredibly easily. Tapping on the chassis, for example, is picked up by the tube. At first I thought there was a loud hum in the right channel, but then my refrigerator shut off and so did the hum! This tube is extremely sensitive... the one in my left channel is fine. Would a tube damper help?
To be honest, from what I've heard so far, I'd be hard pressed to find a large difference between my TS 6F8Gs and my NU 6F8G RPs. Rolling the power tubes had a larger change.
Wow, you've come a long way. Pretty high-end tubes you have there. How is your finger doing? Has it healed pretty well or is it also picking up vibrations like the tube on the right channel?
