I no longer have a 6N6P compatible amp, maybe someone here can use these? Check my signature.

Interesting. Most opinions reckon the earlier versions are "better" and that production values had already started dropping by the early '80s in USSR.

Are your tubes 6ZH1P with OTK marking?

Hi I'm new here... have a LittleDot Mk III and a pair of Senn HD579 that I like quite a lot…

After reading the article on the tube rolling for the LittleDot, I decided to try the Voshkod 6ZH1P-EV to replace the standard 5654 driver tubes since they seems the nicest of the lot in the “95” category.

My question, will I have to change jumpers positions for these or they are the same as the 5654 ?

Thanks in advance !!

No jumper changing needed. Same as the 5654 This Post is very helpful on the topic.

Thanks, I red the article and I was not sure what they meant by « factory configured » just wanted do be sure...

Are they good upgrades ? In the article they where rated 95/100...

Another question, any gain changing the « power tubes » ?

The jan5654w are my second best. But if you go with the Mullard M8161/CV4015 you will acchieve higher dynamics and a tad of better bass. They are fantastic!! Also as you raise the volume, all frequencies stay together, the treble doesn't run ahead leaving the bass behind neither will the bass run ahead of the treble. So I can blast my ears and not get ear fatigue because the treble ran way ahead of the rest of the instruments. As for power tubed, I use the 50 bucks super tubes which are Russian Sovtek cryoset matched and these supplied a little more overall power output over the regular gold grid Russian power tubes.

The Voskhod are very good as are the Mullard 8100s but both for different reasons. One tube that (to me) has the best characteristics of both of these is the Yugoslavian 6HM5 which (surprisingly) is not reviewed in the original post. Again, no jumper change is required for these.

yep 6HM5 is the best driver option before entering C3G territory.

And a smaller version https://www.ebay.co.uk/itm/EC900-6HM5-Lot-of-four-4-tubes-EI-Yugoslavia-Philips-construction-1987/261599117610?_trkparms=aid=222007&algo=SIM.MBE&ao=1&asc=43630&meid=55af112840db40f58032ceb808f3a0a9&pid=100005&rk=1&rkt=3&sd=251611916081&itm=261599117610&_trksid=p2047675.c100005.m1851 ? Has someone compared with former "taller" 6HM5? I own these small 6HM5, they sound slightly bright. BTW I am burning-in Mullard 8100 ..... superb .

 

[sghound]

yeah the taller ones are legit.

 

[Johnybuchar]

Ok I will complete a collection . The small EI 6HM5 tubes sound very good too but aren't all-rounders as e.g. Tesla 6F32 for my ears.

I have a pair of short bottles manufactured by Siemens and I was not impressed. However, I had no idea that EI manufactured the small bottle version and thus I can't say how they might sound.

Yes, I've only recently started seeing the short bottle Ei version. Wonder where they've been hiding.

 

[frogmeat69]

Have some 6DT6A Sylvania tubes, and can't remember what settings, and if they are compatible with either the 1+, Mkiii, or both.
And for the life of me, I can't remember the page with all of the tube settings, sorry. Please help, lol.
