It looks like you don't understand what mail reader is. Just remember, there are other OSes than Windoze. There are also text mode mail clients that doesn't show all those behemytes of stupid html

I've had a problem similar to yours a few years ago with a 8340B. Swapping modules didn't help. It turned out that some of the feed-through caps (from the modules through the main PCB) had become

Are you using a mail client that doesn’t keep threads together? Resending all of that stuff seems wasteful, it’s not as if the previous messages disappear into the void… Any sane email client

That should have said : I for one just delete threads that DO NOT include prior continuity...more is the loss

_*AMEN ! *_ David K , Mr List Owner: One of things that changed from Yahoo to groups .IO. IN yahoo when using the website interface? it automatically included the prior message(s) when replying, with

Look at the YTO alignment - put a detector on it and look at slope of RG output (unleveled). If line is relatively smooth, alignment may work, if you see "squiggles" possible YTO problem (still try

Check for AC ripple on the power supply rails.

This is the problem when people insist on not quoting the original message and appropriate replies. A little net etiquette goes a long way and reduces questions and confusion. Glenn

I didn't have this specific one but I did have a similar issue with 8340B going unleveled in Band 2 - The solution to stop the unleveling (but not to get the output back into spec) was to reload the

I think 4401 is a typo -- it is a TO-92 transistor and original post was about 2N4101 in TO-66 package: pdf.datasheetcatalog.com/datasheets/newjerseysemiconductor/2N4101-2N4102.pdf There is no 2N4401

Note that the 1884-0065 is not shown as identical to the 2N3670 in the HP transistor cross references, so it may be a selected 2N3670. Dale H. Cook, GR/HP/Tek Collector, Roanoke/Lynchburg, VA

I had several fuses on A18 blown as a result of the misaligned connector to A17, I replaced them all. One of them was hard to get which was a 1/4 ampere fuse. I am currently reassembling A17 as the

Hi Scott Thanks for your input, But the 8663A originally has a SMPS, same PSU thats in the 8662A. Three of the voltages, -40V, -10V and +20V go trough a linear regulator board, that I do have, and

I assume you have checked all the 5 fuses on the A18 board? If the fan works it means one of the negative supplies is ok (pre-regulator at least) but there are 4 other fuses measuring on the large

I will have to get back on what voltages I measured, however at the time of the incident which was some time ago, I recall from memory the fan came on when I pushed the power button but all the LED's

what voltages are you measuring on the 5 supply rails on the edge of A17? remember if you decide to take the power supply out and disconnect it from the instrument (ribbon cable that goes to A5)? you

I performed a different test to check the 3 2N4101 SCR's, thanks for the correction. I powered them up with a DC supply and the load was a small bulb at 9V, when I touch the gate the SCR latches and

I think you are going to want better supplies than the inexpensive mean-wells SMPS, HP used linear power supplies for a reason and that was there are no HF components on the DC supply rails to cause
