I agree with the Ken Rads, just received 3 NOS 1943 6C5 for $9.10 each tax and shipping included Cheap thrills, check! You got a great deal @mordy !

My pair, which I like very much, have boxes that are whiter but with the same text. On top of them there is also the same text but SC961A where we now see the US anchor. SC for Signal Corps 'OTK'.

Yesterday I was rolling some small power tubes. First up is the Mazda 6DR6 which is a EL81 variant. It's good but my score is a conservative 8 upon 10. Next was the el cheapo 6P14P aka EL84 and this is a 9 upon 10. 6P14P is really good. Amazing sound from Ultimate with that. My drivers have been Philips EC86 all this time. Get some EC86 and 6S3P guys. They are life changing tubes.

Very noice Mazda 6DR6.


Philips EC86 and Mazda EC86 in Ultimate.


Philips EC86 and Reflector 6P14P in Ultimate. Remember 6P14P are also life changing tubes and it's only $13 for quad.

Hi Matt. Beautiful, enticing photos as always.

Do 6P14P powers utilize same adapters as EL84 for use as powers in UltimatE? Also some have noted EL84's high gain can restrict volume range...is this applicable to 6P14P as well?

Thanks Lory.

Same adapters as EL84. They are essentially russian EL84.

Regarding EL84's high gain restricting volume range - not in my experience.

When I said not in my experience, that's because I am using Susvara.

EL84 gain is higher than other power tubes. This is where you can use lower gain 'drivers', such as 6K6gt in the 6J5 slots.

With 6k6gt and 6P14P, using HD800, my volume is ~ 10am. With Grado GH1 it's 9am. With Susvara it's between 12 noon and 1pm.

Another tube to bring the gain down further is to use EL32 as drivers.

Is there any tube that Ultimate doesn't do well? None. Both 6k6gt and EL32 are excellent sounding driving 6P14P.

Visseaux 6k6gt and Reflector 6P14P. I'm using Susvara. You can see my volume is between 12 noon and 1pm. This is with the notoriously difficult to drive Susvara.


Mullard EL32 smoke glass and 6P14P. EL32 has more gain. My volume knob is between 11am and 12 noon - with Susvara.

Almost a year now and I still find Ultimate amazing sounding. That is unusual.

Now I'm about to do something stupid or clever. I'm going to replace Mundorf Supreme SGO or Miflex kpcu-01 with Russian FT-3 Teflon caps. It is claimed that the Russian can hold up a candle to the VCAP Cutf for peanuts price. The burn in time is supposed to be a ridiculous 1 year.

Oh well if it doesn't work out, I'll just change it back after 1 year.

Which capacitor do you prefer, Mundorf Supreme SGO or Miflex kpcu-01? So far, I think I like Mundorf better. I can feel the human voice and a better sound stage.

Yeah I like Mundorf better but some days I prefer the more relaxed tone of Miflex. They are both good caps without going overboard.

I would go for the Vcap Odam if you want to go one better than the Mundorf, one costs $90.
For $180 it's a good investment that will be quickly forgotten.
It will also be very superior to the Russian.

I don't believe that the Russian can come close to being a threat to the Vcaps.
I wouldn't believe the person who put the flea in your ear.

What the Vcap generally has in its favour is that it also drives less good tubes and conjures up something that you unfortunately don't get on other caps.
It is rather the case that the tubes have to be of a certain quality so that they perform well together with non-Vcap caps.
I have already observed this with Euforia and Ultimate too, exactly the same game.
That's why I get a satisfactory result here, especially on Ultimate with less good tubes.
What the Mundorf doesn't do, the CuTF does.
EL12N RSD is again a good proof, at the beginning a bit analytical and sterile on Vcap Cutf, better on Mundorf, after burn in the tubes, back to Vcap and WOW...
It's not bad on Mundorf, but the last spark of clarity, stage and staging as well as details is actually better on the Vcap, but both are close, so personal listening preference also decides.
I also maintain that the Jupiter will be better than the Russian cap, that would also be an option if the odam is not an option, the costs remain the same.

I think I remember somebody saying that capacitors are not important, and you adjust to the sound...

The Russian FT-3 is free. I'm testing it.

If you have just one pair of caps ie you don't have a choice then you're right - you adjust to the sound but we all know by now that caps do sound different in the same amp. However it is anyone's interpretation as to which is better - seems that way.

Just bought a pair of Russian G-807. @crakers7 did you like those?

YEP, they sounded good , yet to do a side by side comparison yet though with all my other 807's , I am away at work for another 3 weeks , so no tube rolling for me for a while

Believe the hype, GEC A2900 are spectacular drivers in UltimatE. Here is Heath (Mullard) EZ81, GEC 6V6G, GEC A2900 & Tesla EL34 (Roznov):
