Here's some of my 6SN7's + others.There's another complete layer of mostly 6SN7's below the one shown in this box.

I also have another smaller box of 6SN7's

Are you sure they are all "ECC" adapters? It would seem more likely that two of them would be "5687 adapters" & one would be an "ECC" adapter.

I ask because the "ECC" & 5687 adapters are not inter-changable and both are 9 pin mini's to octal.

(although it is not impossible that all three could be "ECC adapters" either)

They have "ECC" engraved on them, and they are of different color to the 5687-adapters I have. I also asked for getting 3 of them with the amp.

Well, it seems that one is defective. I can't make it work, so I have to talk about this with SP.

sounds good!

Don't worry they will replace the defective one

Anyone with a surplus of tubes:

Got any 6SN7 VT-231s for sale? Which ones? How about TungSol 5687s?

Email me or send me a private message.

Hi all,

I'd like to add one more thing to my MPX3 SLAM.
It has the automagic voltage control, so voltage isn't an issue.
What I'd like to add is a gain socket adaptor.
It looks like the ECC1 supports some of the best gain tubes, but the ECC2
supports the 6DJ8 and I have some killer nos Mullard CV2492s that I use in my
XCANv3. Does anyone have experience with the 6DJ8 family in the gain
position?
I'm currently leaning towards the ECC1, since it is known to support such good
gain tubes.

thanks!

I didn't realise there were two different ECC adaptors.

Have I missed something?
post #307 of 780
Is the ECC1 the one that takes 12au7? Then ECC2 is really different, if it takes the 6DJ8.

I've been dealing with J Petrie @ SP.
I asked about adaptors and got this email in response.
Here's the amp I'm (anxiously) waiting for. I don't know if any of the extras
are needed for any of the adaptors to work. I can only imagine the heater
making a difference at least for the fact that the {6,8,12}xxx are all listed as
direct plug-in.

MPX3 SLAM........... 1199.00
Ultimate Power..... 285.00
Jensen Caps......... 154.00
Auto Heater.......... 499.00 (Magic is expensive!)

Dunno how much of this is new... but hopefully there'll be stuff in there to
make some new experiments possible.
I also said I thought it would be real cool if they could have >1 driver socket
and allow you to switch back and forth with a switch. But I'm sure if they
ever decide to do so that I won't be able to afford it.

And after all of this, I'll probably love the stock tubes and never change
anything.

Enjoy!

Oh!

There are quite a many tubes to try! ECC99 is listed multiple times, I see.

You will love tube testing, I think it is as much fun to find a tube combo thats works in your rig, as finding new music!
post #311 of 780
i agree, you will love swapping tubes.
it is VERY advisable to get a few sets.

someone else once wrote in a review of a "higher end" headphone than they had before "hey, i never knew that there was a saxophone in this piece."

sometimes hearing things just a littttle bit differently makes you hear different parts of the music. swapping tubes allows this small change with just 1 pair of headphones.

"I didn't realise there were two different ECC adaptors."

It's news to me too! Will the "ECC2" work with all MPX amps, or only certain ones?

So I kept my MPX3 Slam SE after all...and I'm so glad I did. Now that I have a little bit of time, tuberolling is so addictive. Especially if you have most all of the popular tubes in 12v form . I'm using it now with HD650s instead of L3000 (the sale of which went to fund some Spendor S3/5's and a Bel Canto amp). I don't have speaker cable yet, but I can't wait to hear the SE as a preamp.

I haven't done a lot of hardcore listening yet- I've been too schizo with tube selection- but one thing I feel confident in saying is if you're looking to expose the sound of your gain tube, 6BX7's are it. I've tried all the possible output tube combos (including 5687s), and they're remarkably transparent, at least tonally (I don't have a good feel for detail/resolution yet). In fact, the Hytron 12SN7/6BX7 combo was slightly cold to my ears.

Also, the Tung-Sol RP just sound right. That is all.

Thats what I think too. The 6bx7gt has almost no discernable character of its own and just passes on the sound of the gain tube.

The 6N1P (I would only use the black plate version from the 60's) and 6BZ7 should work since they are the same pinout as the 6DJ8.
