They will.

Has anyone with a 12v option tried the 13D7?

Has anyone tried 8SN7's? I didn't realise SP did an 8v option

Has anyone tried the 6922/ECC88/6DJ8 in an SP amp yet?

I am interested to know your thoughts on the 7062 as a input tube, as that could well be my next purchase.
I tried an Amperex 7062 in place of the 12au7, and I didn't like the 7062 with the 5687's nearly as much as the 12au7. To it's credit, I found that 7062 to have a fairly smooth and uncolored sound (perhaps one of the more uncolored tubes I have heard), especially at the high end, but it seemed to lack the punch at the lower end that the Tung Sol 12au7 gives me. It's not bad with the 5687's, but I prefer the 12au7 more.

I then switched out the 5687's with some Amperex 7119's (keeping the 12au7 as the gain tube), and this was probably my favorite combination of everything I have tried so far. It's very similar to the 12au7 with the 5687's (the 12au7 seems to drive the overall sound), but it has a little more depth to it (though it might be my imagination.) Voices in particular, both male and female, seemed to be "right there" with this combo, and I found myself really getting lost in the music.

BTW, when I was putting in my ECC adapter back in my amp later tonight, the plastic pin in the center broke off. I assume that as long as I line up the pins correctly that this is not really a problem, right?

The way the original 12 volt option was done you could use 8 volt tubes by simply replacing the 12 volt supply with an 8 volt supply. You can add a 24 volt supply and do the same thing for 24 volt tubes too. The 8sn7's I have found were all 8sn7gtb's .... so I never investigated them.

Which brand of 7062 are you using?

The Amperex 7119's are very revealing but not over the top. Detail lovers will be very fond of this tube.

Broke the center pin off .... rookies!

Yes the adapter will be fine. I think some supply houses even sell a center pin replacement. I know I saw one somewhere. If I remember where I will let you know.

Has anyone got pics of the new style SP adaptors with the SP logo on them?

There are some pictured on the Florida meet thread

I broke the center pin on a nice Mullard GZ34 once when something fell on it. I super glued the pin back and it worked great. You could also also use a small dab of JB Weld as it resists heat well. But like Earl mentioned, there are some places that sell a small piece with holes to fit over the pins and the plate has a center pin. I have a metal base GZ34 that someone broke the guide pin on so I got it real cheap on Ebay. The tube was like new and works perfect. I think I paid 20$ for this great metal base 34.

I know. I'm so ashamed. Actually, though, I think this is one of those instances where there was an imperfection in the plastic, as it broke while pushing it in to the amp and I was not applying very much force at all. (Although I have been working out a lot lately, so who knows.)
