Michael, I was indeed planning to substitute burnt Tantalums, by similar ones,albeit with a substantial higher working voltage. This is a proven repair method in REVOX, STUDER audio equipment where

Roy, thanks for asking. I'm in outer East Kishniv... Actually Dallas, Oregon 97338.

Resistors are not that far off to cause the issue you are seeing. First check if the vertical deflection plate is connected to the output of the vertical amp. Sounds unlikely but there were cases of

Mark, You are absolutely right that I want this rather than need it, and I don't really want it all that badly (as I said, I have another scope that does everything the 485 can, only better). You're

well q387 and q386 test good,the resistors seem ok to me bar the ones measuring 57 ohms,would being 6 ohms high cause this?

Deflection plate disconnected trumps bad amplifier. Harvey

I don't know if you have actually opened it up to take a look around, but if you haven't, you should check whether one of the deflection plate connections has come loose. I've encountered a handful of

The more things you have to debug at once, the more difficult it can be.  I'd go to XY mode and debug using that.  I'd hope you have a second oscilloscope, because otherwise things get

Richard, Try cleaning the switches including the time base contacts. Dirty switches can cause a lot of problems. Cleaning IC and transistor sockets may also or should be done. The power supply

hi all i have a sick tek 2215 scope,the issue is the trace is too low on the screen( both channels affected ),i can only position the trace about halfway up the screen using the position controlls,i

Hi all, I've recently become the proud owner of an early 466 (IC date codes are all '74) that unfortunately is a bit poorly. I've done bits of hobbyist electronics repair in the past, but I've never

Yeah, but when you reach 81 years old, like me, it's all wants from now on out <grin>. Paul

I had to go back and look at my sent folder. Either Jeff is pulling my leg, or someone misquoted me. I was apologizing for crashing (as in party crashing) the thread with a query about the Dual BNC

I see a 7D14 in a photo. If that is for sale, let me know the price. Mark

Dave, I can actually use the J20/7J20 set. I do some calibration work on medical monitors (I am a radiologist) more for research as we have QA folks who do it for all the installed workstation

I am looking for the connector in the 7A11 that the probe plugs into,or the connector and the plastic housing that is partially shown in the photo. Leon Robinson    K5JLR Political Correctness is
