WOW and meg LOL.

A few months back I bought a job lot of valves (unseen) from an old radio
shop for £25. In it was a PX25 in its original box. I sold it on eBay for
150 quid!

"For starters, its midrange clarity approaches, but does not equal the
benchmark of the 2A3. In contrast, the PX25 is a warmer, more luxurious
sounding tube."

Wonder how they have managed to break a PX25 amp to make that true, IMHO
to one thing that a PX25 does more than just about anything else is
clarity (1), makes a 2a3 sound like a el34.

(1) though a 45 is very close, and I haven't tried a 26 yet before you
mention it Andy...

Good man :-)

I should get a copy of John's book, think I will suggest it to my better
half as a birthday idea, she normally buy's me usefull things like cheap
screw driver sets.

Actually thats a tad unfair, the cheep screwdrivers have become a bit of
a running joke.

Getting the new phono working, still a bit of hum to track down (as
ever), but I am quite stunned just how low noise these E810F pentodes
are, huge Gm (50ma/v) and a equivilant noise of about 100R. And they are
cheap and easy to find..

I haven't delved in deeply yet, but there seems to be a great deal of
interest in there for a fettler like myself. I too got the book as a
present - my wife knows I have a surfeit of screwdrivers.

Particularly important in a RIAA circuit.

Did you get the HP334A?
It will give you a great deal of useful information, and thinking
about all that new-found knowledge will keep you awake at night.

Better to spend the money on an SS amp, open a beer, and
telephone for a pizza:-)

No, trying to be clever, I missed bidding by a few seconds. Next time I
will just bid what I am prepared to pay and sit back.

OK, you'll be needing these then:

http://www.artaudio.com/krtubes.html
http://kraudioproducts.com/Kr/ProductMain.aspx?CatID=13
http://rorprat.com/2/NewProd.asp

(Can't see you using cheep Chinky glass - note the tricky 4V filaments and
base choices if you do gofer the PX25...!!)

When you get it done, perhaps you will be able to tell me how the superior
'soundstage' and 'depth' which is the hallmark of triodes can be dismissed
as microphony/reverb when it *doesn't* sound like an Echo Chamber and
manages to leave 'point sound sources' (vocals &c.) planted firmly 'front
and centre' while sending some of the instruments, backing and audience
sounds way off into the distance....???

Or, to put it another way, last night I had two amp/speaker pairings on the
go (I almost always do), swappable at the flick of a switch - my 2A3 SET (EH
Golds) and one of my PP Dynavoxes with NOS Russian 'Radio' 6n3cE (6L6WGC)
valves in it.

I got Swim to have a quick listen and just 'pick the best one' - in a
*heartbeat* she picked the 2A3.. *No contest* were the words (the speakers
are so similar at that level even I have trouble splitting them)....

Brings us to the question of speakers - if it's triodes, it *is* horns, in
my book! No doubt you have access to a pair (or three) of nice Lowther
jobbies?? :-)

Keep us in the picture, needless to say!!

(Here and now, I predict another 'DHT convert'....!! ;-)

Hi Keith. It's still a long way off, with some other good
projects in the front of the queue. I am going to research the thing very
carefully indeed.

and centre' while sending some of the instruments, backing and audience
sounds way off into the distance....???

I have only limited experience of SET (one Russian built amp)
but I was very impressed by its ability to produce small ensemble
classical music in an incredibly realistic way. It was a most enjoyable
experience. This is what interests me.

my book! No doubt you have access to a pair (or three) of nice Lowther

SET people seem to use horns. There is a Lowther club in Stockholm.
I intend to make contact with them, and go to one of their meets. It
will also be interesting to hear the Tannoy Westminster Royals.

Keep us in the picture, needless to say!!
(Here and now, I predict another 'DHT convert'....!! ;-)

Hmm- Hard to say. I have already come up against the limitations
of the one SET amplifier that I have been able to audition.
My own listening room amp is usually a 50W UL PPP amp,
which makes a wonderful job of symphonic material and
the big band jazz that I enjoy. But, it seems to me,
that for certain applications the SET amp might offer a very
musical and realistic listening experience.

Me also. The Chinese have smashed the 'elitist' element of SETs with a
torrent of perfectly OK examples at cheaper than affordable prices, so the
only reason to build/buy/use them is because you *want* to!! :-)

Or not, of course....

(Hard to see the wily Chinee spending time, money and energy on summat for
which there is no *real* demand!!??)

Ahh, thats what the valves in the link you posted were, didn't think it
looked like any PX25 I had heard. Maybe that explains why the
description sounded nothing like the sound of NOS PX25's

I suppose it could be fairly argued that no modern manufactured valve is
going to sound like NOS originals. See this re. KR Valves from
http://www.blackdahlia.com/tipindex/Tip-35/tip-35.html:

"The Silver Night line launched in 1993 has exemplified that philosophy:
good build quality, exceptional looks, and delicious tube sound at a price
that the working man can afford. The PX-25 is built on the same chassis as
the 300B Silver Night stereo amp; the only external difference being the
output tube. Please see my review of the Art Audio PX-25 for background
information on this tube. I was originally led to believe that the amp was
outfitted with Chinese Golden Dragon PX-25s. This is most definitely false.
As it turns out, no true PX25 type is being manufactured in China, and all
current production of this tube in fact originates with KR Enterprise in the
Czech Republic. So how did I, as well as Audion, come to believe in a
Chinese PX25? For starters, there's that prominent Golden Dragon logo on
the glass envelope. Furthermore, I was informed by Audion that when they
originally purchased the PX-25 from England they were supplied in Golden
Dragon boxes and that they were led to believe that the tubes were of
Chinese origin. When this review first aired on the Enjoy the Music site,
both Audion and I received angry emails from Dr. Riccardo Kron, KR
Enterprises, seeking to set the record straight. Apparently a production lot
of some 200 KR PX-25 tubes were sold to PM Components in the UK. Audion
corroborated Kron's allegations and stated that they have recently
established that these tubes were indeed manufactured by KR and were later
re-branded in the UK under PM Components' "Golden Dragon" brand. Regarding
PM Components role in all of this, all I can say is: what a devious sleight
of hand! This is a great looking tube, which uses the original British
style base. Beware of imitations: every KR Enterprise tube is manufactured
with a number code inside the glass envelope. This code certifies the
authenticity of the tube. Dr. Kron tells me that there are imitations
floating around, branded as a PX-25, but with the innards of a 300B."

How up to date these websites are is, of course, anybody's guess...
