Hi Bert, I think you want to send the photos to me, not Lee (Lee was test fitting the feet on his 335). I was the one who sent you the samples. You can send the photos to me at n0dyjeff@... or

Looks like a crystal socket to the right of the variable capacitor. Maybe a 1 MHz reference crystal?

Lee, I received the new feet late today and they look very nice. I should probably send you the pictures off list so please let me know where to send them. Many thanks, Bert

I have 2 DSA601/602's that used to work. One still works but with problems. This is probably power supply problems but I thought I'd collect a few other possibilities before I dig in. Someone may have

It's all in the manual - U160 is a 1MHz crystal oscillator and programmable divider. Roger

I'm thinking there should be an oscillator here? /g/TekScopes/photo/37195/9?p=Name,,,20,1,0,0

I had a look for any old microfiche but did not find any. My Epsom V700 scanner came with a number of film carriers of various sizes. One looked like it could hold 2 microfiche but it was just a

It seems that the same method can be used that transfers 8mm et al movies to digital could be used. In the case of movies a projector is modified; the lamp is replaced by an LED and a camera (USB in

VueScan (www.hamrick.com) works with Linux, Windows and Mac OS X. No affiliation. Just a very happy customer.

Craig, I suppose you then have the software to do the calibration. Any chance you'd share it plus any instructions for configuration and use? Raymond

Hi, I found lots of documentation (not everything..) here: http://w140.com/tekwiki/wiki/THS700 The schematics (bottom sketchy link) show the attenuator as one single square, so no details on the

Very interesting project. This model is my favorite for field use. I have not tried to do any repairs as I don’t know of any board schematics. But have had good luck doing calibration. I have

Hello-- I'll second Merchison's enthusiastic comments-- this application (VueScan) is one of the best software purchases I've ever made! 73-- Brad AA1IP

Thank you @DavidH. That answers my most important nagging question and essentially concludes this inquiry. Thanks to everyone who helped.

If that is a reply related to ykochcal, yes and if it could be determined to work in some useful to help scan the microfiche maybe if you would be willing to donate and everyone could help get it

The common mode input range of the P6046 is only 5 volts which becomes 50 volts when the x10 attenuator head is used. This is typical of other high bandwidth low voltage active probes. High voltage

For completeness, there are a couple of other things I discovered setting up my Fujitsu fi-4530C ADF scanner (Fujitsu makes high quality, fast and compact ADF units that are often inexpensive on

A commercial copying operation should be able to copy these rapidly and cheaply Robin

Thanks David. This is very educational. What range do you classify as low voltage?

Hi all, My new project is the repair of a THS710 I bought broken at a Dutch secondhand website. So far I found three problems: The screen has a 1/2" black bar at the bottom of the screen and it is
