n_maher Posted December 14, 2007 Author Report Share Posted December 14, 2007 I just picked up the driver set from HF. It is definitely the 1/16 size. I'm going to try it in a hand held screwdriver first (depending on my fustration level, then I'll whip out the DeWalt) and will report back.

Voltron Posted December 14, 2007 Report Share Posted December 14, 2007 seems reasonable. I was thinking about something like a 12AY7 driver tube into a pair of 6BX7s. Just curious, do you actually mean the 6BL7GT or perhaps the GTA? If the former, then you're probably the only person I've met that has recommended these tubes. I love 'em, no one else will try them Hmm, I cannot recall. I will take a look at what I have in the tube caddy and report back. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted December 14, 2007 Report Share Posted December 14, 2007 1/16" bit with a ratchet type screwdriver worked like a charm. I tried again with the 1/16" key type and it wouldn't budge and I felt some of the threads strip a bit... I then tried again with the bit and it worked with a bit of elbow grease... so... thanks tkam! Quote Link to comment Share on other sites More sharing options...

Guest sacd lover Posted December 17, 2007 Report Share Posted December 17, 2007 Hmm, I cannot recall. I will take a look at what I have in the tube caddy and report back. No one recommends them because they are very difficult to find. I had about 30 I traded to Mikhail. PFKMan 23 is one of the few who has some of the 6bl7gt's.

I checked and mine are 6BL7GTAs as you suspected. Maybe I need to get some of George's GTs before he sells his MPX3. George, are you reading this? Do you have 4 you could sell separately?

luvdunhill Posted December 17, 2007 Report Share Posted December 17, 2007 Maybe I need to get some of George's GTs before he sells his MPX3. well, it's all a preference thing really... My MPX3 SE is somewhat of a one-off to support this tube. It's in between the "high" and "low" options you see on all the MPX3's with switches in the back. This is where this tube is most comfortable. I think there was maybe one more "switch-less" MPX3 SE out there, I'm not sure though. On the regular high setting it's a bit slow and dark, so you'll have to choose your input tube with care. Amperex 7062 is a great choice, as is the 2c51. It really opens up the door for several input tubes that you may not have cared for with the 6BL7GTA and perhaps even with the 6BX7GT tubes. They are a bit challenging to find... but very possible. I've squirreled away a dozen or so, and know a guy who is sitting on stash of them but is too lazy to sort through them for me... There is a pair on the 'bay now, for what I'd consider an outrageous price... but they are construction matched pairs and from one of the more reputable Ebay dealers.

darkless Posted December 17, 2007 Report Share Posted December 17, 2007 I have 3 or 4 6BL7GT tubes. In my old MPX3 SLAM XLR (not the SE model) I preferred 6BX7GT tubes. Quote Link to comment Share on other sites More sharing options...

I preferred the 6BX7GT tubes as well in my other MPX3 SE models. Problem I'm finding with the SP stuff is that the guts vary so much that this further complicates the whole recommendation process For a lot of people, I think swapping some caps out here and there would make more of an improvement then chasing after some long forgotten tubes Quote Link to comment Share on other sites More sharing options...
Voltron Posted December 18, 2007 Report Share Posted December 18, 2007 Thanks for the info. Do you know the voltage in your middle setting MPX3? My SDS-XLR has a tube regulated & rectified PS, so I can dial in a wide range of voltage settings. I already like the 2c51 with the 6BL7GTAs so I would be curious what the 6BL7GTs are like. As for the fancy pair on eBay, I need 4 so that won't help me much! well, it's all a preference thing really... My MPX3 SE is somewhat of a one-off to support this tube.

tkam Posted December 18, 2007 Report Share Posted December 18, 2007 The GTs will be a little warmer/fatter sounding than the GTAs Quote Link to comment Share on other sites More sharing options...
PFKMan23 Posted December 18, 2007 Report Share Posted December 18, 2007 I'd say it depending on how the amp/tubes are biased. On my amp, on the higher voltage setting the GTs are way too fat and think for my liking but the GTAs are fine. On the lower setting the GTs sound better.

PaulB Posted December 18, 2007 Report Share Posted December 18, 2007 Mine is a switchless MPX3 SE. I've been using the 6bl7gta's but recently got a pair of 6bx7gt's and love them combined with a cryo 396a as driver. The bass impact alone is stunning.
