- I got really excited with 6N2P tubes! Finally I can use them after keeping them in my tube stash last 16 months . Im really excited to try different variants and manufacturers of 6N2P type tube. Just from this Voshod 6N2P-EV example I know this is going to be a very fun journey into the 6N2P rabbit hole, haha! DONT FORGET!! To make sure your amp is having a 6v supply before trying these our yourself! More 6N2P vids in the future! Subscribe for more! :)
Nice sound demos! My ears liked the 12ax7s clean & the 6N2Ps crunchy. 😃
Yes. this is voshod, Kaluga city. EB is more than 5000 hours. If you have any question about Soviet tubes. i can tell you
I bought 40 on ebay. There's a few types. And markings are faded.
- 3 mica grey plate ( voskod? Photon? )
-3 mica silver plate
-4 mica ( 3 on top )
-2 mica silver plate
-2 mica grey.
Is there an easy way to identify these ?
@@soapboxearth2 Don"t you have any markings? Even the dates? 4 mica and dark plate , could have been made also on reflecror (Saratov).
@zubrzubr6769 most are quite faded. I can make out the reflector logo on a couple. And the voskod rocket on a bunch. I xan see date codes on a bunch of them as well.
I guess I was just wondering if the triple mica ones are 6n2p-ev? Or 6n2p-k maybe? Or are there normal 6n2p with a variety of 2 and 3 mica depending on year?
@@soapboxearth2 With three and four layers of mica, i have met В, ЕВ, and Е-ОС. ОС (особо стабильные) is highly stable. They have "silver" plates. With two layers of mica, they were ordinary and with a Soviet quality mark. They have dark plates. The photon and the reflector have a large distance between the digits of the month and the year. v 71 or х 73. And the voshod has them next to it and is usually written with a dash. х-72 or v-77. This is due to the location relative to the logo. There have been changes in the design over the years. But some tubes were produced by чту. Private technical conditions. Batches of these tubes with priority properties were manufactured for a specific customer. For example, for a large batch of measuring instruments, they could have been made for years. They were marked with a rhomb, the letters чту and digital code. Complete with basic marking
@@zubrzubr6769 thanks for the info !
my word, what a drastic difference! i couldnt pick a favorite.
I worked on audio amplifiers in the '70s. The thought of paying the then equivalent of $80 for a 12AX7 would have been outrageous.
Yeah insane prices on 12ax7s! Thats why im experimenting with 6N2P!
i have i think 10 i bought a long while ago....after hearing your test i have to dig them out
Give em a chance! Worth it! And they sure will be longer in stock selling adound then vintsge ECC83's👍
6N2P pour moi, une meilleure qualité sonore, plus d'air
The 12AX7 sounds louder.
I don't hear much of an EQ shift but the volume difference is apparent.
For what I've read 6N2P has an amplification of 98 when 12ax7 has 100. So basically 6N2P would sit somewhere between 12ax7 and 5751. It could be just a hair quiter.. But not to the extent like would be if 12AT7 or even more in case of 12AU7...however the tonal characteristics are slightly different then would be an European made ECC83. I'd say this tube is best buy in 12AX7/ECC83 world 👌
somewhere between, @@ecc8344/
5751 is 70mu
6N2P 98MU
12AX7 100mu
tho these spencs arent adhered to by all tubes. mullard (british not russian rebrands) ECC83 test lower gain than modern 12AX7.
Another great video thank you from England
One might be useful in V1 for dirty sounds to tame fizz or an amp that is too bright. Kind of reminds of the difference I’m getting between a greenback and a Fane F70 right now. The GB has more sizzle and the Fane has a tamer top end but still with a good midrange. The Fane is a great choice for dirty amps that have a lot of fizz or sizzle in the top end and you want to get it out of the way of cymbals etc.
This is the design that Sovtek 12ax7wb come from. Basically same tube but re-wired to go into standard 12ax7 sockets.
Yes! With exception of better materials since this tubes were build for Soviet military :) and Sovtek today is made only for consumer's market :)
@@ecc8344 why can’t they just sell the present Sovtek with better materials? I would pay more money
Well, I guess like everything today is made to be consumed fast so it comes with poor craft and materials...and you dont have to pay more..you can pay less for 6N2P and have a better tube then Sovtek, win win situation :)
@@ecc8344 I bought one adapter. But I can’t use them in my combo with the tubes hanging upside down.
@@voxpathfinder15r you can use a el84 tube retainer for that. Socket and tube together got the same size.
Wow great demo. I like the better separation between instruments with the Voshods, they are a quieter but it doesn't matter really. Please could you tell me where you found your adaptators ?
Hi there! Thank you! :) i've found them on the eBay .you should find it if you type in ; 6n2 to 12ax7" . Cheers, enjoy :)
Ironic your channel is called 'ECC83' but you call the ECC83 a 12AX7. I wondered about these old Soviet era 6N2P valves - cheap and plentiful, now I know they are not a drop in replacement and have 6V heaters. Useful info :-)
I call them ECC83 myself, but most of people know them as 12AX7 so I tent to say it more oftenly to not cause confusion :)
I’m an American, but prefer the ECC83. They are ever so slightly different, and I prefer the European tubes.
His tubes have the Voshod logo... yes, they are Soviet era.
Great video. Thank you
the 6np2 has less top end...warmer feel
No, it doesn't. You need to get 9/10 in a level matched blind test to be even close to sure. This kind of testing is simply bullshit. And i do have formal education on the topic: it is rare to hear differences in tubes of same kind and if you do hear any it is most likely that one of them is defective.
This type of tubes can be used on a Fender Twin reverb? Great video. Many thanks
Hi :) you can put whatever you want as long the tube type is right for your amp. Its up to your taste and what can you find selling around :)
Top ecc83
i agreed with your comments but i struggled
What have you struggled with? :)
to hear the differences there are differences but it took a couple of run throughts to pick them up @@ecc8344
Are they direct replacement ?
No. Different pinout and only running on 6.3v ..so if you want to use them you first need to verify if you amp heater indeed runs on 6.3. . And you either need to get this adapters that im using or re-wire your tube sockets. When it comes to tube yes.. its pretty much ECC83 with exception that this one has 98% gain when ECC83 has 100%. The gain difference is so small you woudnt even notice :)
Does anyone knows where to buy adapters?
On eBay :)
what song is that first riff
One of my riffs..I dont play covers :)
У меня есть много советских радиоламп таких как 6н1п 6н2п 6н3п 6н5п 6н6п 6н23п 6н14п и еще очень много наименований...если нужны то могу продать не дорого если есть к вам доставка
For HiFi use, I think the 6N2P:s do not stand a chance to the 12ax7:s. Lack clarity and spatial qualities
Een Nederlander?
The 6n2p’s are very inexpensive. Just a different heater pin out. No center tap.Order from Ukraine. Great deals and they can use the cash.
Right on!
I bought two boxes of these about 10 years ago, I think it was Bulgaria or somewhere, before the sanctions and they were not even a dollar a piece if I remember correctly. Built one Champ like amp with them and I prefer that amp to the 5F1 I also built.
Awesome! These tubes sound great :)
Perché l adattatore per le 6n2p non entrano direttamente
Yes it does actually☝️
