The new issue Sovtek 6L6WGC is also coin base. The Tube Amp Doctor site out of Germany says that these are the same as 6P3S-e.
Here is the current issue 6L6WGC http://www.parts-express.com/Data/De...2-300_HR_0.jpg http://images.nitrosell.com/product_...GC_Quartet.jpg Here is the older, military 6P3S-e http://rutubes.com/published/SC/html...ig&photoID=839 http://classic-tubeware-kunisch.de/P.../6P3S-E-Q2.JPG |

Speaking of 80's Tube World has some NOS/NIB British Tungsrams that are very good. I've not seen them anywhere else. |

I just found them at Cryoset for $32.99 a pair. He does do thorough testing. cryoset.com/catalog/product_info.php?cPath=22_80&products_id=334&osCsi d=3cb0dd4a329a5e5e14d28a0a4a64393a Last edited by jdandy; 08-22-2016 at 04:42 PM. Reason: active link to non-sponsor seller against forum rules |

What two tube dealers are saying is that the current Sovtek 6L6WGC *IS* the same tube as the mil-spec 6P3S-e. That the factory in Russia didn't change it at all, except to relabel the tube so that its label would be recognizable to modern tube buyers. I've seen various tube amp owners, both audio and guitar, write the same thing.
The "W" in 6L6WGC designates it as military grade, as opposed to the 6L6GC. And then there is the Sovtek 6L6WXT+, which I've seen stated is also the 6P3S-e but in a standard base. Again a military grade tube. Last edited by Bombadil; 08-22-2016 at 04:35 PM. |

You can go nuts chasing and trying different power tubes for these amps. You nailed it earlier. The driver tube makes a big difference and having a good selection won't break the bank, especially when you don't need matched pairs. Last edited by FloridaBoy; 08-22-2016 at 04:55 PM. |

I know a guy who has been in the tube amp business for over 30 years. Has built dozens of tube amps of different types. Restores guitar and audio tube gear.
His favorite tube is the 6L6. And, a surprise to me, his favorite go-to 6L6 is the Ruby 6L6GC-M-STR. A fairly inexpensive tube. He told me that maybe it is a little tiny bit shy of the best NOS 6L6s, but that it is very close and is a great value. It is made in China and is a copy of the Philips STR-415. The Mesa STR-440 is the same tube. He also likes the above Sovtek 6L6WXT+. I don't tend to trust these inexpensive, guitar amp tubes. But perhaps I'm wrong. We are in a golden age of tubes and whose to say that Russia or China can't make a very good tube which is inexpensive? Back in the 50s and 60s, a lot of the tubes which are now pricey NOS, were common and inexpensive. |

And yes, the 5Y3 and 80 rectifiers are supposedly electrically identical, but Dennis and I found that even though the distortion curves didn't necessarily change much, we were able to notice a significant sonic difference between rectifiers.
Understood. Thanks for the pointers! |

Florida Boy: You should get another quad of the 6P3S-E. That appears to be your favorite power tube. The good ones are getting hard to come by.
I know, but there's the question of finding that same quality of the ones you sent me ... |

Based on recommendations by Musica Amantem, I have the following in transit to me: 1980s “NOS Matched Pair USSR Reflector 6P3S-E / 6L6GC / 6N3C Military Spec Vacuum Tubes”, from a USA seller who tested the tubes on a calibrated Hickok TV-7 D/U tube tester. More to follow …
