Jordan, I found the origin of this manual. I bought it from AA4DF site . Since they carefully scanned and sell this hi quality manual (I paid $10 but I think now it is just $4.99), I think it is no

Jordan, I have the service manual in pdf. It???s about 12 Mb. It is a hi quality scan that I downloaded some time ago, I don???t rememeber the source so I can???t give them the due credit,

d.seiter@... escribi???: Mmmm... let me see... yes, the exoticc elastomeric switch! Well, it has also quite a lot of exotic hybrids :) Regards, Javier --

One of my two was DOA through this. Inside the switch ("do not open" says the manual. Ha!), the cunningly shaped elastomer had a tear in it, and was failing to operate two of the contacts. A bit of

Deane is quite right. Think about it this way - when the bridge diode turns on, the capacitor charges up through the secondary resistance of the power transformer and the reflected primary resistance,

I wouldn't say that the ESR meter is "required", but it sure makes life easier! Plus, it's a cool kit to build (if you happen to go that route...;-)) -Dave

I decided to pull out my 067-0587-0x's and realized that I'd never tried the -02. Of course, I find it has problems, like the gain steps aren't there. I only have the manual for the -02, but I assume

That may be so, but when repairing relatively modern equipment with many many caps that need to have low ESR for the circuit to work (e.g. switching voltage converters) it is absolutely great to be

This reminds me that I need to do a "group cal" on all my gear. I have both fixtures, but I just never get around to it. The individual scopes are all cal'd, but when I start swapping plugins, I

Anyone got a manual for a DM44? Owners and/or service. ~Jordan~

Hello, There was also an entire batch/lot of problem 465B crts from back in the day. One of the problems was spot size and ability to focus. Many were replaced under warranty by Tek. I remember

I posted a photo of the blurr to my album. You can't see it well in the pic, but it looks much worse and fuzzy/blurry in real life. It looks like it is focusing right, there just seems to me a shadow

Hello Scott, Thanks for posting the link to the Anatek ESR comparison page. I have both the EVB from Portugal, and the CapAnalyzer 88A that are on the Anatek comparison page. The EVB is another modern

Take a look at: http://www.fullnet.com/~tomg/tekclean.htm where there are procedures that try to address this problem for both the 465 and 475 scopes. When I had a 475 I did this procedure and it

The key thing about the cal fixture is that it calibrates the mainframe independent of plug ins. So you adjust horizontal and vertical gains, and trim up the rise time of both vertical and horizontal

My 465b won't focus quite as clear as it should. Doesn't matter where I adjust the focus or astig control. It looks like there is a ghost image of whatever I am measuring. So the trace/waveform

See this web page http://www.anatekcorp.com/testequipment/esrcompar.htm - There is what is known as the 'Bob Parker' design this is a cheap accurate ESR meter upon which countless commercial

Using higher Voltage/Capacitance ratings usually is not a problem especially since many of the old can type electrolytics were rated -20/+40% of nominal rating. Higher voltage is usually ok as long as

Hi folks, Thanks for all the tips in this forum. I am just stating to work on a used 7603 with three plug-ins (7A18A, 7D15, 7B70) I acquired cheap as a second scope with a 442 I got also got cheap
