If you want to provide information about a particular instrument and am not completely comfortable with English I, for one, would be more than willing to “edit” your entry to make it readable. The

I can believe that if the LF13333N is going flakey that the display might jitter some, it's used to switch between sweep and digital signals. Dave toggle quoted message. . . It took very long to

If anyone else is interested it looks like he has these AVR clock kits back in stock and available to order online. Every time I've looked they've been out of stock.

Another small update on this. I found the clock was running fast, somewhere around 30-60 seconds per day. So I set out for a solution (low cost, of course.) I found an old GlobalSat BT-359 in a box

The 7854 power supply I'm working on has a lot of rusty nuts and bolts. I don't want to slosh something like phosphoric acid around in there. Are there any rust removers that are OK to use around

Generally chemical rust removers are a problem, unless you can liberally hose the unit down with a rinsing solution and a water displacement solution. I tend more towards oils and mechanical removal

Evaporust is a great PH neutral deruster. It only attacks the rust. I would remove the rusty hardware and soak it in evaporust. Then remove and wash with water then spray with a silicon based

Hi John, Nice idea to use a BT-GPS. OTOH, 30 - 60 s/day fast is a suspiciously/impossibly large deviation for the built-in quartz crystal oscillator. 350-700 ppm?? No way... Are you sure C3 and C4

If it was my scope, I would just buy new hardware. 73 es HH, Dick, W1KSZ wrote:

Hi Garry, I printed my own operators and service manuals for my 2465A DV. Maybe you may want to print your own like I did. I am like you as I prefer reading from print rather than a computer screen.

Raymond, Yeah, everything is installed (no leftover parts, lol) and I triple checked all components before soldering to make sure I had the right ones in the right place. It may not be quite 60

Hello Guys, Has anyone researched and found a good replacement for the Hall-Effect sensors in the Siemen's fan motor #1AD3001-0A? I am rebuilding my fan motor because it started making some noises a

Tek content:  I made the VFD enclosure for this project from an empty 5K scope carcass that was reduced to about 5x6" and shortened. I was hoping to move some of the 1/4 turn locks, but found that I

HI Ever heard of capacitative coupling, it even works at 60Hz. You must have a death wish if you use un grounded machinery. George G6HIG

Most of it is so well rusted it's not possible to remove it at present. Dave

Why do you think that? Raymond

Good, thanks :-) Yes, Kurt says by case with bad pictures: better a bad picture as no picture. I has few CRT, (it was donate from a german metrologie for me) and i don't know: Which instrument uses

I was hoping to have them installed by Christmas but they're so fiddly it's taking ages. The first one is in there but I've been struggling with the second one and am experimenting with different ways

On the local auction site (http://www.allegro.pl) here in Poland, which generally has a paucity of test equipment, I've just noticed a 647 in working order for sale. In anyone in Europe is desperate
