N17-S-60615-3661
SWITCH, ROTARY
1 EA.
WECO # KS-9497 , L-1
NAVY ORDER #N1265-35101 (P)
NAVY TTEM 1
WESTERN ELECTRIC CO., INC.
KEARNY, NEW JERSEY

So British valves with Cuban stamps and an American box. Very strange.

Cheers,
Andy.

Oh, this is great Andy, I am going on the hunt. What an odd bag though as only last night I saw Shikada San post pictures of the new tubes he has and there were a pair of WE's which I have never seen before in our type of tube. What is odd as well is that they are Brimars in a mil spec box but without mil spec printing on the glass like my brimars have.. some hunting I a' go! smily_headphones1.gif

Andy.

That is pure inspiration! I bet he could do that and I bet it would look fantastic.. I also bet he could do it with the 05's as well which would look great as well but the 06 I feel would look the best as it feels more skeletal.

Thats wonderful GG, I found him to be fantastic in dealing with my problem, as I type it is in the air on the way to Japan!

version 1:

- then the neutrik jack could be build into the amp instead of the 3.5 mm output jack drilling the nessesary hole.

version 2:
- moving the power jack from the rear position to the front drilling a hole above the input jack
- drilling a hole for the neutrik 6.3 mm jack where the power jack was as additional headphone out

so my first cradle prototype maybe would be an easier solution.

I agree Bmichels, it would be hard as everything is pretty tight in there as I found out when checking the bias of the batteries.

GG, I think the solution the Shikada san has ended up with is a slightly longer chassis to acomodate larger headphone sockets and RCA outputs. I think he tries to keep the cable runs as short as possible.

I wonder, could you take a picture of the inside of your amp and post it. I want to see what the new HP socket looks like!

Also, personally I think the power jack is in the right place out of harms way, it would be so easy to confuse it with the input jack and thus short out the amp.

I wonder why  shikada san left so much room empty inside ?

 

He could really have made the TUR-06 even smaller by filling all the inside like he did foir the tU-05 !

 

See bellow my attempt to squize it by just moving the volume pot above the battery (and 1/8 jacks side by side).  ALL Fit perfectly and the deept is reduced by 20%  tongue.gif

My TU-05 should be sent this coming week, from my recent email exchanges with Shikada-san. He is such a sweet guy! Email communications with him is always a pleasure!

 

This is one of the most anticipated products of the year, for me................

post #1579 of 3704
that is wonderful news! I agree in all my contact with him it has been nothing but a pleasure and if something does go wrong he sorts it out immediately. In the end though he offered I covered the shipping. He is after all a one man band starting out and a $100 is a big pill to swallow when your self employed as I have found myself when I started out.

ianmedium - i did nothing with the amp up to now because this will fill the whole day. version 1 everything is so tight that the neutrik jack cannot fully inserted so needing a distancer, version 2 i am thinking about but the cableling at least would need some shielding because the output signal cables are just 5mm away from the preamplification stage, don't want to get any crosstalk.

 

for the cables - the cables are longer than absolutely needed (no direct point to point, but everything is nicely bundled together), don't know which cable type, but thin up to the output jack (in comparison to the input cables and headphone cables, at least mine), i think of internally recable the whole amp when modifying it with the neutrik jack.

i have to correct my last statement:

 

had a second look inside the amp:

 

i was wondering about the yellow cable:

 

but found it just to be the power for the led's of the volume knob. the signal cables are under the volume knob, shielded, short and nearly not to see.

 

the other cables are as short as possible but long enough to remove all screws of the housing or in other words just right to assemble all parts and then put the parts of the housing together.

great idea and photo editing work !!!

 

i have no photo editing software on my tablet, but when i saw the picture i thought of something similar but moving the right pcb down just above the battery, the volume knob top right and the connectors left above the tubes. then a new housing, and you have a very compact portable version.

 

bmichels - is it great effort or can you post a picture with the components placed this way ???!!!

Thanks for the inside shot, I can't quite make out the HP socket though. But I Notice the he has changed the battery bias compartment from what I have which is an open box with some tape holding the batteries in. I wonder how one checks and changes the bias and batteries with this new box?

Great job on the photo editing! It looks like it would work a dream. Might be worth sending him your edited image!

Andy, so far regarding your tubes I saw this expired listing on ebay for Western Electric US made, Brimar branded tubes!
http://www.ebay.co.uk/itm/PAIR-WESTERN-ELECTRIC-USA-MADE-BRIMAR-BRANDED-TYPE-83-301-A-RECTIFIER-TUBES-/271241323697?nma=true&si=IpEtDXvmVISTYbVw%252FF4eS0JhW1U%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

This also is a clipping I found from transparent sound.com
"History
"Western Electric" in the USA opens in May 1883 a small office and store in London. In September 1925 the International Western Electric Company was bought by the "International Telephone and Telegraph Company (ITT)" and since then this undertaking in Great Britain which has grown substantially is named "Standard Telephones and Cables Ltd. (STC)". STC uses first the brand name “STANDARD” for their valves. In 1932 to 1933 the valves are called “MICROMESH” and from 1934 on “BRIMAR”. The Brimar valve and cathode-ray tube division was sold to Thorn Electrical Industries Ltd. in 1960. Between 1950-1960 STC played a major role in the British semiconductor research."

You have probably along with my Marconi's the most historically interesting and puzzling tubes out there!
I still cannot find anything about the stamp on it!

OK! I think the stamp is a red herring!
It has franking marks and I just did a search and it is a Spanish stamp.. I think! The other thing it may be is a stamp that acts as a seal for customs use in the perfume trade but that is purely speculation! biggrin.gif

Here we are GermanGuy:    Your solution on the right and mine on the left.  Your solution has to be larger because the volume knob is against the tube wall.

 

Note: I did not understand where you want to put the connectors, so I did not implemented them. Let me know and I will add them.

Excellent sleuthing and great deduction Ian. Thank you so much for shedding a modicum of light on the valves provenance.

 

I too wondered whether the stamps were added to artificially hike up the eBay price, but as each valve was only 4 Euros, I dismissed this theory rather quickly. What intrigues me is that the paper stamp appears to have been over-marked with an ink stamp, which suggests authenticity to me. Anyway, I have emailed the valve photo's to Steve at Mullard Magic and eagerly await his expert opinion.

 

Cheers,

Andy

Ahh, Andy, Meastro Steve will be sure to know. I was thinking, I wonder if the addition of the stamps was to do with reducing microphonics or tinging noise, if so and you find these tubes quiet then we have the beginnings of some very decretive valve possibilities..
Penny Black Mullard anyone? biggrin.gif
post #1589 of 3704

Oh if only it were so Ian. Imagine the artistic/audiophile crossover potential for valves `stamped' with an authentic original artwork by zeitgeist artists. I suggest that we trademark this idea now and contact Charles Saatchi soonest. wink_face.gif

 

Cheers,

Andy.

Ahh, I can see it now, what with GG's innovative ideas and our decoration of valves we will rule the world I tell ya, rule the world, BruuHaaaaaaahaaa! evil_smiley.gif
