I'm thinking about the EML 5U4 or 274B for the rectifier.
I can't find any mesh alternatives to the output/input tubes, I wonder if any exist? |

Anyone here with experience with a 6N8S? I ordered 1 today to try as a driver tube. I hope it is worth the $.

How much did you pay for it? I've seen the Russian ones going for $2 each. I know the older, metal base ones are pricey.

Metal base, round holes in plates, quoted as NOS,... $75+shipping.

I have a pair of EML 5U4G tubes and use them from time to time. I also use NOS Brimar, GEC, Marconi 5U4G tubes. I find the EML 5U4G´s just as good as the NOS tubes, nice glow due to mesh. The only down side is their size, they are BIG! Me? I'll pass. However, I have considered them. EML does have mesh plate triodes. There are no mesh plate pentodes or any other mesh power tube that will work in these amps. |

Could this be the same people? amazon.com/sp?_encoding=UTF8&asin=B01E57OA72&isAmazonFulfille d=0&isCBA=&marketplaceID=ATVPDKIKX0DER&orderID=&se ller=AT9HPTJQR9BRT&tab=&vasStoreID Looked on the auction site and found a previous seller that went by Salience HiFi but no recent activity. Quick google search turned up the Amazon web store. Looks like they may have moved there business from the auction site. If so, I am gonna order one of the UK CV181 to try on my 45 SET. PS: Still in FL? Im over on the Treasure Coast myself. Last edited by jdandy; 08-21-2016 at 08:10 PM. Reason: active link to non-sponsor seller against forum rules |

I can (I think) hear differences when I switch between 5Y3, 5V4, 5U4G/274B, 5U4GB (I think I hear a tiny difference between this and 5U4G, but wouldn't bet money on it in a blind comparison), and GZ34. But within rectifier tube types, say a vintage Sylvania 5U4G vs a vintage RCA 5U4G vs Tubestore Preferred 274B, I am not convinced I can hear any differences. Many tube amp owners say the same. So I've decided to not spend a lot of money on rectifier tubes. Dennis has told me that he considers the low cost JJ GZ34 to be very good.

However in my comparisons of 6SN7 tubes, I did consistently hear differences. I have 7 of them, and each one sounds a bit different, a couple of them a lot different. A couple have brash upper midranges which can be pretty aggressive. Another one is both recessed on highs and flabby/loose in the bass. The difference is immediate.
Despite their reputation as frequently being noisy tubes, I haven't found that to be the case with mine. I turned up the volume a long way with no signal and could not hear any hissing, pops, noise at all. And this is through Focal speakers with their detailed tweeters. No humming either. I have found that I can "tailor" my sound a bit via my selection of 6SN7 tube. |
