I'm looking for a source of 9 pin sockets, both molded plastic and

who's cheaper than AES? Thanks.

How about the 6BM8-SVET, hi-mu triode, 7 watt power pentode in a 9 pin,
made by Svetlana at $9.00 ? Or the 6HF8 ?
Specs, anyone ?

Well, yes. 6BM8/ECL82 has a design maximum of 300V and 550V at cutoff.
6AB8/ECL80 is a smaller triode-pentode but has a design max of 400V
(pentode).
More data can be found at http://www.algonet.se/~janax/tubedata.htm
Note that 6AB8/ECL80 has a common cathode, limiting the choices a lot.

Well, I will fire up Big Bertha Radiomarine on 3579 tonight,

Then after that over to 7050.

Yeah, I noticed the band was heavy into QSB, and was fine as long as the
SSB did not come up, but when the SSB did, the average voice modulation
tone was square in the middle of the passband on the R-388. That was one
of the very few times I have ever had trouble on cw from an ssb station.
Oh, well, I must be getting old or pfutzing my hearing. Then, the skip
went long, and we thought you were having rig trouble or something.
Your AF-67 was doing a fine job, and Doug/K7YD's machine likewise.
Ol' Neal/N4HAF always blows the front end outta the RX, as does Dale/AD4YH
when he's aboard for the watch. Ol' Dale's DX-40 runs like a stripedarsedape
going QRQ 35 and above and makes my day. I was hoping more of the West Coast
crewe would be there, and we did pick up Jim/W7HPK in Seattle, around
0400Z. I did not hear Vic/K2VCO or Jim/W1HIJ, another pair of CWist regulars.
I know, it is that sinkhole in the LA basin with its smog ether sparker
destroyer.

I have not had much success on 80M lately, but a few are sometimes there
on the TV rockko QRG 3579R545. 7050 has been working out pretty well.
Earlier on, the QRS folks are there, and later one the QRQ folks come
along. But, we gotta get's more o' de Glowbugge and CWist crewe signed
aboard for the watch. It seems just a few of us diehards are about.

Hey Glowbugs and CWists! Now this here feller has got a fine howdy do
way ta sits back on da veranda, tips a fine mint julep in the grand
southern bayou tradition, and dances the ol' dit ditty on the Bugge, and
with a grand ol' AF-67 and PMR-7 mobile pair of fine and goodly stock.
That has gotta be one o' them thar epitomes de Hamdom.
Lessee, I gots one o' them thar folding Army antennamastthingies......
Now a piece of pipe for a base, and a clamp to hold the mast base on,
and it sounds like a liesurely way to pick up on 40/30M, in the settin'
back style..... neat! Alas, the ol' deck table would croak if I drug up
the SRT-14 or even the SRT-4. It might handle the Hartleys or the old
ArcusFivus gear, without folding, tho. Nah, mebbee I need ta bring out
the GRC-9 for that work.
> Tell Neal he was belting one in, and on his last xmission he QSBed
> down to nil!
Neal/N4HAF always has a pretty fine signal, an' that thar dit ditty dancin'
o' his is pure sweet musick outta his sendin' iron.....
I dunno why the SRT-14 did not put out more. I had about an amp of RF
in the antenna RF ammeter, and that was all I could get out of her last
night. I may have to check the rectifiers again. It eats those silly
things, and I need to complete out the solid stating of those vacuum
rectifiers. That is me one howdydoo to sandystate stuff.
Doug/K7YD came on with that 4-1000 and was quite QSA5 here.
So's all ye Glowbugge and CWist folks, rallys ye round de ol' 40M QRG,
an sees ifs ye canst rattle an' bang around de SSB mush. The Glowbugge
crowd comes aboard anytime after dark, but seems that 0100 to 0200 is
the best time, and then the QRQ CWist sparkers come aboard around 0300.

Beware of Hartleys, Regens, and other assorted ancient

p.p.s. I am QSP this via both the Glowbugs and CWist lists because we
share a common CW mode and a common QRG. Also, a lot of the
Glowbugge folks are fine QRQ CWists in their own right, and
I am of the opinion that we can have a QRQ roundtable with
Glowbottle gear or sandystate gear, and all have a good time.
Blame that combo squarely on ol' Boatanchor Bob, fer sure.
It is good to combine the CW artists on the QRG, to keep the
spirit o' de ol' Rattle an' Banging on the Brass Monkey, alive.
On CW, the ancient rigges still puts out fine ether sparks.
Besides, that will help keep that raucious silisidebander stuff

Well BA Bob,
There are four things holding me back and then I'll soon be on:
1. A honeydo list a mile long! (can't do much there but whittle away at
it)
2. A 3 1/2 month old (but she goes to bed pretty early)
3. Awaiting me 40M rocks from Phoenix Xtals (the postman hates me)
4. A ground system (my wifes teli rolls and squigles when I TX)
But I'm getting closer to gettin' on, and your notes to rally the troops
get me fired up to get a little closer every day, even got the straight
key polished up! I've got a DX-20 I'm just dying to try out - then onto
a HB rig of some sort.
See ya on 7050 soon....

I think it's a commercial station. GKE1 Portishead, England comes

Subject: Svetlana Glowbugging Power Triodes
I just received the Svetlana data sheets on many of their tubes.
There are some neat things there.
1. The SV811-10 Low-Mu Power Triode:
6.3v 4a filament
800v/160ma plate
standard 4 pin basing and socket just like a type '10.
Now Hear This:
2. The SV572-10 High Performance Audio Power Triode:
6.3v 4a filament (same?)
1000v/210ma plate
*** standard 4 pin basing and socket just like a type '10.
This would be ideal for a single 4-pin socket style rig that you
could interchangeably swap a 10 watt or a 50watt bottle, by merely
changing the tube. Alas, the prices are a tad steep, but not too
much out of hand for the diehards --- 30 bucks and 57 bucks respectively.
The sizes of the tubes are the same, but the elements in the 572 have
that nice biggie graphite cathode inside.
Sounds like a neat set of tubes.

Subject: "Better" 6T9, maybe.
I don't have a high voltage 6T9 equivalent, but maybe something "better";
The 6T9 was primarily used in audio frequency circuits with the triode as a
voltage amp and the pentode as a power amp. For RF a 6KY8A may be a better
choice. It was used in combined vertical/horizontal deflection circuits
and is a Hi mu Triode/Beam Power-Pentode. The max plate voltage on the
Triode was 250 and the Beam Power unit was rated at 135, but there isn't
any reason why you couldn't run 120 Volts on both. The beam power side is
good for 12 watts.

Yet another alternative to the 6T9 is the 6GW8/ECL86 of Orphan

is rated at 9 Watts. There are two specs for plate voltage however. The
"Plate Supply Voltage" is rated at 550 Volts max but the "Plate Voltage"
is only rated at 300 Volts. Could someone explain the difference between
the two specs?
