Actually right before I posted this thread I emailed him:thu: Just thought someone on here might have some inside information. They're still pretty new so if someone on here did have a go at these tubes and liked it, I'm sure we'd have seen a thread about it Link to comment Share on other sites More sharing options...

It's stated not to use in V1 slot, so unless they fix the problem I'm staying clear from them. Let me see if I can find TGP thread Edit: http://www.thegearpage.net/board/showthread.php?t=438130&page=29 I think that was it Oh and this:http://www.thegearpage.net/board/showpost.php?p=6390444&postcount=539 Link to comment Share on other sites More sharing options...
Members boogieman75 Posted July 9, 2009 Members Share Posted July 9, 2009 Speaking of pentas does anyone know where else you can still get older generation 12ax7? i.e. gen 6 or anything prior to gen8? Doug does not have them listed but I didn't know if he has em on hand and you just ask or what the dealio was. Link to comment Share on other sites More sharing options...

TechTube and Penta Labs are different I was referring to that gearpage thread because ken361 had a link to the TechTube tubes in his post.

I don't think those are the same as these new Penta's. Someone correct me if I'm wrong. They are a whole new 12AX7. No relation to the Penta's or anything else really. Shipped to the US 1 new 12AX7 TechTube is $70 rounded off. Link to comment Share on other sites More sharing options...

Members solarburn Posted July 9, 2009 Members Share Posted July 9, 2009 Ouch! How do those compare to NOS? IMO NOS still reign but these are suppose to be better by a mile than any NP tube out there. Comparable to NOS but we will have to have some real world tests and use out of them to see. It would be only speculation and hype right now.

Members ClutchX2 Posted July 9, 2009 Members Share Posted July 9, 2009 I just bought an assortment of those pre amp tubes, but I didn't get them from Doug though. I haven't installed them in an amp yet either. They are going in on the next tube change. Link to comment Share on other sites More sharing options...
Members solarburn Posted July 9, 2009 Members Share Posted July 9, 2009 Link? I want to hear as many results as possible, but from what I read so far it doesn't look promising. No one has tried them yet there but we just started talking about them. I'll give you a link to the thread so you can mark it for any info you may want. Beginning of NOS preamp thread: http://www.marshallforum.com/marshall-amps/3824-preamp-tubes-who-what-when-where-why-how.html Last couple of pages is where you should find us beginning to talk about it.

Members FastRedPonyCar Posted July 9, 2009 Members Share Posted July 9, 2009 The new rubys are not new. they're new to doug but I've been using them in my amps for about a year now and they are incredible. I think the AC7's are the best current production tubes on the market. They're super quiet, have been gigged with more times than I can count in 3 of my amps, have done equally as well in my tube mic preamp which stays on around 7 hours a day and they're inexpensive. Jim from Cryoset was the first guy I could find that sold them. I found out about them after Adam Jone's (TOOL) guy from the Diezel service dept in Cali retubed our other guitarist's einstein with a set of the AC7's and the ruby el34B-STR's. I got a set for the nitro and officially retired my NOS RCA's, Bugleboy and Mullards. for high gain, yes they are that good IMO. for lower gain stuff, the NOS tubes still have a bit more going on in the mids and upper midrange as far as creaminess and sweetness but once it's at gigging volume or moderate to high gain, the differences are nearly impossible to hear even when A/B'ing a re-amped recording of the same amp, cab, etc. and for what it's worth, After about 8 months of use out of one quartet of the AC7's, I retubed with a fresh set and noticed ZERO difference in clarity, punch, power, etc... the old ones were still as strong as the day I got them so they went back in and the new set went into some other amps.

So whats the main differences between the AC5 AC7 and select and high grade?I have an AC5 select which I assumed those were just good ole Shuguang C9, similar to the regular Penta Labs 12AX7 Link to comment Share on other sites More sharing options...
Members solarburn Posted July 9, 2009 Members Share Posted July 9, 2009 , similar to the regular Penta Labs 12AX7 Me too. They sound good too but these AC7's sound like they are worth trying. I don't really need high gain though and I like the dynamics of the NOS I have cause I usually play blues/rock. Link to comment Share on other sites More sharing options...
Members FastRedPonyCar Posted July 9, 2009 Members Share Posted July 9, 2009 I didn't notice any difference between them. I've got a few AC5's. Cryoset's website has them listed also as HG and HG+ variants... maybe jim from cryoset has more insight.. or doug now that he's selling them. I'm guessing though that they're basically the best of the best chinese tubes. Link to comment Share on other sites More sharing options...
Members Guiary Posted July 9, 2009 Author Members Share Posted July 9, 2009 So then if Ruby are supposed to be the top choice Chinese tubes and so are Penta Labs = same tube ?!? Jumping to conclusions, I like the yellow of penta labs Link to comment Share on other sites More sharing options...
