$1.25 per tube, any quantity. Shipping is a USPS padded flat rate envelope. 
$5.30 inside US,  $12.95 to Canada or Mexico, and $16.95 to any other country.

[neonixie-l] IN-9's for sale

[Dan Foster]

Hello,
I have a few (10) IN-9 Bargraph tubes that I no longer want, thought I'd 
ask here before I list them on eBay. Anyone interested?

Re: [neonixie-l] IN-13 Spectrum analyzer

[Dan Foster]

I'm assuming you're talking about the analyzer? The spectrum analyzer chip is 
MSGEQ7, which comes in DIP-8 and SOIC-8. You can find it on sparkfun in the DIP 
package, but the SOIC version is harder to find. I'll dig up the place where 
you can get it if you want.

[Dan Foster]

Yes, I've seen a lot of neat ones on YouTube. All of them are rather large, 
though. My board is 3.2 x 1.25 if I remember correctly. So hopefully that's an 
advantage.

Re: [neonixie-l] IN-13 Spectrum analyzer

[Dan Foster]

As for why 7 channels, I found a little IC that breaks down audio into DC 
components (7 to be exact). I have found a fft that runs on AVR 
microcontrollers but am not sure of its accuracy or how quick it is. So for now 
I'm using the IC. I will definitely investigate the fft when I can.

[neonixie-l] IN-13 Spectrum analyzer

[Dan Foster]

Hello everyone,
I am thinking of selling a IN-13 spectrum analyzer, either fully assembled 
or in kit form. I've just ordered the preliminary boards to get the final 
prototype together, but it would be 7 bands with a 3.5mm jack input. 12v 
input from wall power, and possibly a mini USB port. The final product 
would be around 3.5 inches long and 1.3 inches tall, with the tubes going 
up from the front. Below is a render of the enclosure to give you an idea 
of how it might look. I'm still deciding on whether or not to leave the 
sides open. Let me know what you guys think and if there is enough of a 
market I will produce some.
Thanks!
Dan

Thank you so much. Hopefully I'll get this thing hooked up shortly...

[neonixie-l] 13LO7V Oscilloscope Tube

[Dan Foster]

Some time ago, I purchased a 13LO7V Russian oscilloscope tube. I
haven't been able to find much information on it, so I figured that I
would ask here. The only datasheets supplied are in Russian, and while
I understand most of it, a lot of it still doesn't make sense.

eBay page:
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&item=250714332006&nma=true&rt=nc&si=GjWLRlYcnR7h3GMwZBDVVa5fMGU%253D&orig_cvip=true&rt=nc

Datasheet scans:

 www.radiolamp.ru/sprav/elt/13lo7_3.gif
 www.radiolamp.ru/sprav/elt/13lo7_4.gif

Here's what I've gathered:
Anode 1 - 600V @ -50 to 250μA
Anode 2 - 2kV @ 500 μA Max
Anode 3 - 4kV @ ? μA
Anode 4 - 8kV @ ? μA
Heater - 6.3V @ 600mA
Modulator (?) - -80V @ 5μA Max (1.5 MΩ resistance?)
Deflection per volt is 0.24 mm / 0.3 mm for x / y

Thats about it. Any additional information or insight would be
awesome.
