WTB: WIN7 Laptop USB2, w/Charger etc or Trade for Tubes

Hi Y'all,

Maybe someone out there has a something like a Dell Laptop with
win7 on it that they aren't using any longer. I need one so that I can use
my QA400 analyzer through it on a USB2 port.
charger that works etc.

Probably needs the 8MB RAM and whatever video memory will
work. The larger the screen the better.

QA400 doesn't work on WIN10 machines.
It worked with WIN8 but that is problematic.
with WIN7 it worked just fine.

PM me with what you have or post a pic here etc and price.

PS - I'm on a very limited budget.

Open to trade for tubes or for sale.
Matched NOS Pairs:
7581A NOS,NIB Philips ECG7581A for reference only ebay $429.99 LINK
Mine are triple matched, factory, distributor, then in actual amp. I'd let these
pairs go for $325 plus actual shipping. While they last.
Gm = 4700, Ip = 50
Amp match varies a bit as it's not as controlled
as a precision matcher. These voltages were measured
through a 10 ohm Dale RN65 to ground and subsequent
extrapolation to current draw at 450V if I recall.

Tube were burned in for approx 30 minutes to stabilize,
then also checked for noise, and microphonics by chopstick
testing. I guarantee these tubes!

5 - .439 = 43.9mA
6 - .420 = 42.0mA


7 - .426 = 42.6mA
8 - .404 = 40.4mA
9 - .419 = 41.9mA
10- .423 = 42.3mA

The only non-performance issue that I noticed with
these tubes is they've been in in-home storage cabinet
and each tube has been protected with a green puffy
styrofoam peanut. They exhibit a slight fog on glass
appearance that I wiped off the two tubes in the pic.
Along with the very gentle wiping, some of the green
logo edges started to lift also.

6V6 GT NOS Mazda "Guerre"
This pair only, $125 plus actual shipping

Gm = 26.0, Ip = 3.10
Gm = 26.0, Ip = 2.90

Cheers,

Once upon a time, the first poster in a thread could edit and add to it,
reconfigure it so that things wouldn't be burried way down yonder here.


I had to quickly develop the pics and here they are.

It's Sunday night and I'm just hangin' out
Lookin' for a place to party
I jumps into my ride and I hits the road
'Cause there's only one place to go
Down to the nightclub (NOT) Ooh, the women be righteously ready and pretty
Down to the nightclub (NOT) We go bump-ty, bump-ty, bump'
Bump City!
 
You can download Windoze 7 from Microsoft (unless they pulled the ISO image as it's no longer a supported OS). You can then buy a license key on eBay for not very much money. The keys I've purchased have all registered just fine with the Mothership, so I figure there's someone out there with an insane bulk license (or keygen that sneaks under the radar, I don't know).

Anyway. It's an option.

Hi Tom,


Yes, thanks for that. I have two spare WIN7 licenses, the laptop that I need to
work with it is WIN10 and I can't dump it and run win7 on it as I now have
apps that work and run with win10. I can chance screwing up that laptop.


There is hope in the near future.
 
You can run a virtual machine on your windows 10 laptop and load windows 7 on that.

I had to do this not that long ago to do some jtag programming with software that would only work on windows XP and was looking for files in places that windows 10 got grumpy about, so the virtual environment was the only workable solution aside from looking for a really old computer.
 
I have a (broken) Lenovo 15" laptop that runs Win7. I put it away 2 years ago when I couldn't figure out how to repair it...it's sat there until just now. I don't even remember what the symptoms were. It looks nice but when I plug it in the only sign of life is one LED on the front (i don't hear any hard drive or fans spooling). If anybody feels inclined to make a repair attempt it's up for grabs for the cost of shipping. OP from this thread has first shot. I also have a RAM stick i bought for it (can't remember what size or why I bought it for that matter)
