Ok.. I had a few bad transistors in the mix, but the one that was in the unit checks out ok. I tossed a small handful to alleviate future issues. I spent a little time simulating this and from

If someone wants to send me a URL, I could try pulling the file from a fast connection.

I'll check these over lunch. Interestingly, two of the original transistors in that spot cause the 3a fuse to blow. Now sure if thats indicative of something else going on w/ a good transistor in

Bill, 22V on the emitter of the driver is very strange. It seems that the pass transistor Q2 has an open base – emitter junction and a shorted collector base junction to come up with those

Thanks Michael, here's a recap what i'm seeing around the -12.6v line currently: .65v at base of q11 sensor amp, .275v on collector. Driver has 22v on emitter, .27v on base and -.27v collector. Not

Bill, OK so you have the early version of the supply. If you give me the voltages at the base of the driver transistors I can perhaps give you some more pointers. Mike Sent: Thursday,

The zener string is holding for now. Not concerned with it just yet. I've managed to fix the 248v rail by replacing driver, a zener and a si diode. I did however lose my -1.5v trying to sort out

Or use "wget -c" which is similar to what Dr. Kirkby said but using "curl". For me archive.org also fails in 90% of the cases but I retry it and continue using wget and -c option. If you don't use

having received no feedback, I continue with a brief update on my attempts to bring my HP8595E back to its former glory 3 Summary and state of the art: it all started with the failure of the main

Hi. The Neon reference tube is indeed known to "go funny" after some years. The isotope contained to lower the striking voltage only has a 10(ish) year half life.? After 20+ years they can become

I have a spare complete lead set (16715-68702) here in the UK – open to offers. Includes ribbon cables flyleads, grabbers etc.. David Sent: 29 August 2024 16:51 To:

Hi Adrian, There is a good cable compatibility table in the "Logic Analyzer Probing Solutions" that Paul posted earlier in this thread. There are four cable types that I've seen that have the 40-pin

My unit is 1615a prefix, it did have the zener and it was measuring closer to 100v instead of the expected 83 or whatever. It has since been replaced by a pair of diodes that bring it to 89v but I

Bill, There are 2 versions of this supply. There is an early version that has a neon tube as the reference for the +100V supply and a later version that uses a 9V temp compensated Zener that is

Mark, or anyone - Do you know if there's any significant difference between the various long cables ? I have some woven cables with 40 pin 0.1" connectors both ends. I think these were used on the

Looking at the -12.6 line since its the simpler of the remaining two. Q9 Driver I see about -0.62v on each collector / emitter (expect -6.61v) Q10 Current limiter, 0.004v at base (expect
