I have a pair of RD27AS on the way, which I gather are a more powerful version of the standard PX25. Ziti will be an interesting shootout....

Let me say this. I had a unit with no volume on low it for me hurt dynamics on high it was as it should be. If I were you use the volume in the player to adjust for balance
It does not have any negative affects until it’s lowered let’s 20 % but this is player sensitive. May I ask what player you are using ? Also Roon vol control is not a good one where I river or hq player are good ones
Al, still running Roon, so I don’t attenuate digitally. I’ve wondered about the affect of the switch, but hadn’t experimented yet. I appreciate your comments. Was actually hoping someone would go there.
So, flip the switch to high output, drop in some 242’s, and then what, try a passive with a buffer stage instead of an active preamp? Or get HQ player?

Yes, Please get adapters, this is just too interesting not to do and compare the various options you have :cool:

And see if you can get the RK 5u4g rectifieres as they really sound quite a bit better than the regular KR 5u4g.

Yes, you should give the 242 a try. If the 242 works in your system, then it is magical :eek:

I think my Pacific has that internal gain switch but I haven't found the neccessity to try so far.
Next time I have it open I will have a look...
Well, ok. First Steve needs to try his RK PX25 to prove that he prefers the KR242. Then he can sell his used RK’s to me, at a discount because they will then be used.;)
There are some used RK 5u4g’s available to go with the one I have. But then I’ll have six KR PX25 and two KR 5u4g that are homeless. Then I’ll need a pair of RK 242.
This is good business for KR. o_O

What's the difference between RK and KR variants of these tubes?

Other than price, higher vacuum, zirconium coating, thicker glass, different shape.

I see you have an Allnic L5000 DHT. I’m currently auditioning an L9000 OTL/OCL. Pretty amazing piece.

For me the KR242 is a must have "in my system"

The realism it creates never ceases to amaze me

PS..Don't forget to use Herbie's tube damping rings though View attachment 66051

Only necessary because of the microphony all KR tubes exhibit.

Replace with Tesla AD1 and microphony will be so low these won't make any difference.

I am not trying to be a know it all I am trying to make people realise the truth. Because it is true.

The rings I would bet cost much less than the tubes do and it allows me to use a tube which, in my system, has made a huge difference in the SQ. of my system Plus I’ve said countless times I’m not a tube roller nor am I a cartridge collector. The two carts I have now give me everything I want. So also does the KR242

Allnic has really spun off many pieces of product. The L9000 looks like an intriguing design. I am completely happy with the L5000. It works with 3A/110A in both slots, which decreases the current and increases the output impedance, but increases the gain by about 6db. It also sounds better that way for some reason. Usually, with DHT, when you increase gain, you lose a bit of sound quality. The 3A/107a works well in the first stage, as well as some Western Electric variants, and the dutch postal tube the PT8, so there is some tube rolling options.

Just can't beat that DHT midrange.

Holy smokes. Just got my mov px25 up and running. Replaced out the rk px25. No critical listening, but immediate pop in the mids and bit more detailed. My 2 channel setup is for shyt right now so hard to judge soundstage but feels like might have moved me up a couple more rows.

oh forgot to add, thanking the good lord the tubes arent microphonic.

I haven’t heard the L5000 so I can’t compare. But this 9000 is more dynamic and lively than anything else I’ve heard. it also teases out details and separates tones that were previously blended together. I’m rather glued to it. This variant uses the 6080 twin triode but the L10000 uses 300b.

I am very happy with EML 45 MG Ked recommended to me, together with KR 5u4g RK they have tone, timbre and a bit less gain than my former PX25 - which is good.
I’m tempted by the new 242 RK series as some of you suggest they are less dynamic than the regular KR242 and sound warmer.
I tried KR 242 in my Big 7 and it was clearly too much gain in my system -they sounded shouty but in the same time were very transparent and resolved.
Do you think that with Pacific I should give the RK 242 another try?

Yes definetely you should try it out but afaik RK242 are unobtainable at the moment...
But in general all tubes we discuss here (KR PX25(RK), 242(RK), 45GM, ad1, RD27) are plain phenomenal ;)

I have had a Manley Neo 300b preamp/headphone amp also for some years, that I use as a gain stage for various purposes regularly. However, unlike KS Parks L10000, it is 6sl7 input, is not balanced, and has cap coupling but also includes an optional output transformer coupling.

In my usual odd meanderings, I looked at the circuit diagram, and it also accommodates 182b, 183, 6b4g (like 6V 2A3 with adaptor) and 6b5g(adaptor)as well as 300b, all of them, of course, sounding different. 182b and 183 are 45 tubes with 5V cathodes. I have a pair of ancient 182b globes that I can pop in when I want that real antiquarian 45 effect.

Do you know why? :eek:
And if this can change some time in the near future?

I had got the 242 over to yours. It didn't work in your set up. If you want to try it again, either if you change your integrated, or you can get Lukasz to add the 242 resistor to your Pac.

The RK 242 you can try but it will be different.
