Sorry to hear about your foot Bryant but I am very glad that the Super Silver Supreme arrived in one piece and obviously singing sweetly with your Susvara.

Take care mate, we're getting old(er).

I have questioned my decision to buy GEC KT66. It is a big, beautiful tube, sounds very clear, clean, airy and elegant. But I could not find any drivers that gave it a thumping, heavy-footed sound. It hits just like a welterweight, not a heavy weight, until I find this short little dude.


I do not have ECC35, but Westinghouse 5691 (RCA made) really delivers and elevates the GEC KT66 to the top tiers that belongs to EL39, EL38, EL3N etc...

The magic of synergy. No tubes are good of their own...

The Caldera and Verite Closed are tied for first place Nick. A bit more bass presence in the VC, a bit more upper midrange & treble in the Caldera. Imaging good in both, just a bit more vertical height in the Caldera, the Caldera timbre sounds more even by a bit.

The VC are amazing with a very minor mod done to them. I haven't even really considered purchasing a new/different pair of HPs since I modded them quite awhile ago. I've actually never had a pair of HPs take my desire away to look for a new pair before like these have.. love em!

Idk, I heard something just a little bit ago that may bring this into question!

.... although nothing, no tube mix can make a Philips ECG sonically tolerable. The choices are: off switch, dustbin.

Ah, its just a little project I am working on myself.. have been designing and building my own tube amp circuit. Currently the circuit is on top of a piece of plywood for prototype/testing purposes and I have thought of a different way one can use those dissimilar dual triodes (I am sure I am not the first with the idea), which could likely be able to use only a single dissimilar dual triode in an amp and get wonderful results.

Essentially, using one of the sections to act as a CCS (instead of providing amplification) for the other triode's load, and it provides the amplification.

You mean socially tolerable?

My Philips Austin Powers 807 came today in a rusted vintage tin container.

 

[Deleeh]

Never see Phillips 807.For sure is rare.

Is it the one with the blue label where you mean as 12at7?
Some have also asked how you see your Ultimate Mini with the Hp8, have you been able to gain some insights in the meantime?
You seem to like Hp8 more than Ultimate, or is it deceptive?

@UntilThen show us picture from the beauty 807,

 

[UntilThen]

I was so eager to listen to the Philips 807, I didn't take a picture but here it is in Ultimate. The tubes are a bit shorter than the Radiotron 807 but size is no indication of sound quality.

What is strange is that my Philips 807 has USA printed on the tube. I have seen Made in Great Britain ones and in the picture I attached below is one that says Swiss Made.
So I guess my 807 is probably RCA and RCA is the first to make 807. They invented it !

 

[Deleeh]

Look exciting.
Swiss made is also new to me.
I can imagine that Switzerland had nothing to do with the Second World War and that's how contracts came about.
It looks like Philipps had a hand in it.
Is the other tube made in us or also Switzerland?
You can't see it so well on the picture of the right tube.
They can definitely be fun.
Hope you enjoy it.

I can't wait to see if my belated birthday present arrives from England today.
It was stuck at German customs for 10 days for nothing.
I have ordered it:
KT63 Gec Black glass
EL84 Mullard (slightly used)
6k6 Sylvania and as a replacement Visseaux
EL34 Svetlana Winged C Nos
6v6 Mullard
6SL7 Gt Tung sol Black glass
13D9 Brimar which also passes as a 12At7 and I have heard a lot about this tube.
From Italy and there again Oops stupid, the parcel is stuck 25 km from my home in the centre.
It contains KT 88 SED Wingend C.
So the very popular Russian ones from St. Petersburg, which have not been manufactured since 2012.
If you are interested in the KT63 you should hurry.
Because this tube, especially the Gec, is very rare and because they have gained popularity in the Aegis amplifier, generally the KT63 genre.
As Zmf will soon be selling the Zmf Aegis as a finished product, they could be out of stock very quickly.
If the parcel from England actually arrives today, KT63 will be the first thing I will hear.

You are getting a lot tubes all of a sudden. Both my 807 are USA.
