OK Jeff, Happy New Year to you and all that read this message. I got it. The .ASM lighted up on my Explorer as an Assembly file for Solidworks, hence the...
Hi, No schematics at all. Thanks anyway. CT1EBHT Rui Jorge Martins Proudly user of FT-ONE, FT-980 and FT-2000 73! From: hp_agilent_equipment@yahoogroups.com ...
Hello Rui, what you need is the CLIP 5958-7817 ! Try to buy from ArtekMedia / Dave for arround 20 Euros ($27.5). I used there services and the quality is...
Hello to all, FYI, I also have an 8750A with a network analyzer module available if anyone needs it. Regards, Jim [Non-text portions of this message...
Hi all, As I wrote some time ago, I am working on an 8562A. It had a faulty reference oscillator module which has been replaced (thanks Stan!) and now at least...
Hi all, when switching between S-parameters the relays start buzzing loud. This does not happen always, but quite often. Have checked +/- 25V supply, because...
Scope the voltage to the relays. It has to be dropping out or the relays would not buzz. Testing the capacitors won't give you the whole story. -br4...
See service manual troubleshooting guide: A3Q25 - A3Q26 function to prevent over voltage and over current in the driver amp. A malfunction of the protection...
I suppose this is slightly off topic, but i feel this is the best list to ask. Sometimes i patch the vertical out of my SA through and amp and some custom...
... Note that Scotty's is a "traditional" swept analyzer (like the 8566/8566). This is a fine approach -- and typically provides the best dynamic range -- but...
Hello Oz Did you get your 8753B to work with the v3.0 EPROMs from ko4bb WEB-site? I seem to have problems - not booting properly. Does anybody know in what...
I need a part for my 410B VTVM. Does anyone have a 25 ohm 5W wire wound pot used in the 410B to adjust the voltage of CR1? (HP stock number 2100-0870) It...
Yes and I need a pair of 6CW5 tubes for my 200CD. As for your pot, if you can't find a donor unit you may have to alter the design a bit. A slide wire...
Hi David, I have a 410b that could become an organ donor if you don't come up with one elsewhere, this weekend is the soonest I would be able to dig it out...
Bob, You should be able to find a pair of NOS 6cw5's on ePay, or from various tube vendors for $20 or less. They were a relatively common output tube in lower...
The 410B is now working. It appears the problem was a short in the 25 ohm WW pot, R49. Cleaning and fiddling around with this pot seemed to clear the short...
This is great news. Way to go David. You can best believe that if it happened once, it will happen again. The next lucky sole will benefit from you toil and...
Chris, Thanks for the reply. I want these tubes for a 200CD that I rarely use. The oscillator works fine but has a tad more distortion than it should,...
Another possibility would be to use an old school approach and use something like a PLL tone decoder, e.g. an NE567 at the audio output of a receiver. When the...
