Either of those adapters should be fine. It is my understanding that even though your laptop adapter can put out 3.5 amps. the tube will draw only what it needs, and therefore, for example, the voltage regulator should never see more than 600ma for a 6SN7

like the one to the right...

Ceramic octal plugs have arrived, now for the B9A's to get here for 12AX7 / 6DJ8 adapter building.

This morning, I received an adapter to allow 2C51/396A/5670 tubes to be used in a 9-pin socket configured for 6DJ8, and I am pleased to report that it works perfectly. With this it will be much easier to roll and compare these tubes with the 6DJ8 types. As I write this I am listening to the Western Electric 396A and it sounds great. :)

And in the picture below you can also see the 1 Ohm 3 Watt resister I am using to reduce my heater voltage down from 6.7 volts to 6.3 volts. (Maybe we should have a contest to see who among us has the craziest and ugliest configuration? lol )

Hello guys!

 

I have a question:

you know, back then when we had only limited tube possibilities discovered, EF91, EF92 and EF95 families, there were some kind of reference tubes like the Mullard EF 92, Voskhod 6ZH1P and so on....

I now enjoy the sound of the Voskhod, but I wonder if there are any new tubes THAT REQUIRE NO MODDING, which sound better than these Voskhod's?

Maybe someone has experience with these tubes and knows what would be a great ugrade?

 

Thank you very much!

 

(And yes, I know I am not up-to-date tube-wise here :D)

6DT6, 6HM5... BOOM!  My personal favorites of yesterday! 6DT6's try to get RCA's or Sylvanias... the 6HM5 try to get the tall tubes not the short, squat ones... they shorties sound like poo...

6DT6 - use EF92 setting

6HM5 - use EF95 setting

Thank you for these recommendations!

 

So these are kind of endgame tubes when I don't want to mod something?

And do they improve over the Voskhods in every aspect?

 

Should say that I like a crystal clear sound with great dynamics,good punch, maybe a hint of warmth.

So the Voskhod's were great til now, but you know, upgrades are so tempting......;)

You have to remember that everyone has different ears and different gear. So one person's best-ever tube is another's so-so tube. Generally, most who have heard these tubes felt they were better than any EF91, EF92 or EF95. Will you think they are? The only way to find out is to give them a try. And fortunately, they are cheap. So if you try them and still prefer your Voskhods, you haven't lost much. Happy tube rolling! :)

Thank you again.
How would you describe both tubes tonality wise?
I think I am trying one of them then.

Lol, read it starting from the end of the thread, it'll be more useful to you (though pretty destabilizing at first!).

Sorry, but I haven't listened to those tubes in a long time..... However, you can search this thread for more information:

The newer tubes start at around page 50 and they are enumerated on page 77 and as Audiofanboy stated for the best and more expensive tubes start reading from the end of the thread.

Hi CollectoR13,

 

Buy these tubes from Yugoslavia; offer $4 or $5 each - free shipping. Asking price is $6.95. Look up on Ebay:

 

6HM5 /6HA5 / EC900 export quality audio triode tube / NOS / FREE SHIPPING /

 

As a bonus you will get a 1 second fireworks display when you turn on the tubes. (Don't worry, they are designed to flare up for quicker start, and it will not damage anything)
