Hi,

I assume you're looking for a dealer inside the USA?

Have you asked Ned Carlson at Triode Electronics?

Cheers,😉

I looked casually a couple of months ago.
The only place I found them was here:New Sensor

I was hoping I could turn up someplace else.

Frank; Checked all the local sites including Ned's but found nothing. Is this a tube that is normally available in Europe?

Dougl; Checked the New Sensor site but didn't see it. I understand they were Svetlana Tubes and some data about them appears in their tech bulletin # 52, but that is as far as I got.

Hi,

He,he...Continental Europe, yes....But I guess that wasn't the question.

To be perfectly honest with you, I've never even seen one here.
Occasionally a dealer has them but there just as rare here as they are at your side of the pond.

I'll check around for you tomorrow but if unsuccessful there are a few USSR dealers that do carry them.

Other than that E-bay sellers offer them almost daily.

Cheers,😉

Try this:Svetlana

All the way at the bottom. $5.80 ea

Doug; Thanks a lot, don't know how I missed it when I looked at the site; must be old age!
Thanks Again.

Frank; Found them thru doug's thread to New Sensor, but thanks anyway for the help!

An even cheaper alternative is to use US TV damper diodes such as the 6CJ3 at 3 dollars a pop, like Lynn Olson.
No top cap to worry about 🙂
Noval rather than Magnoval sockets.

My choice over 6D22S and MVs in a family environment

[Peter Menting]

Brian; thanks for the suggestion, I believe that I'll try them instead. At $6/ pr it sure beats the price of a 5AR4 that I currently use.

PY 500A

Are PY 500A any use to you?

I have around 8 NOS if you need them

 

[Peter Menting]

Alastair; Thanks for the offer but I think I will take Brian's suggestion and go with the 6CJ3. The issue of the top cap and the 42Volt heater would be a bit of a hassle1

Regards,
Pete

HOLD ON...

Hi,

Noval rather than Magnoval sockets.

MAGNOVAL for the 6CJ3, no TopKapi...😉

 

[Brian Clark]

Oi oi oi, I guess I don't really know the difference

I had somehow got "novar" in my head in place of "noval", which was then mentally displaced upwards in size 😀

What I DO know is that Russian magnoval bases are unsuitable for US valves. I know because I mounted some then plugged in 6CJ3s - wiggle wiggle wobble wobble

[Peter Menting]

Brian; How about the magnoval sockets from antique electronic supply; are they any good?

Hi,

Well...That turns out to be quite correct anyway....Dang #@!!! I should have known.

The 6CJ3 being a n American type it's not likely to be a magnoval pinout but NOVAR.

I had second thoughts aleady but Duncan amps wrongly describe it as magnoval.

NOVAL are the small 9 pinner such as 12AX7A/ECC83 etc.
Magnoval or big noval is used by the 6KG6/EL509 (mostly TV tubes)
Novar was also used by TV tubes, often dissimilar triodes etc.
Both NOVAR and Magnoval are quite similar in size but not at all interchangeable...
When forced into the wrong socket reliability problems may crop up.

Here's a picture of both side by side:

The GE 6CJ3 data sheet didn't help - it says

Base - E9-89, Button 9-pin

and under the basing diagram

EIA 9HP

Hah!

The sockets I found I had bought many years ago - for PL509s
