Zen, Thanks for your reply. Table 3-3 of the manual suggests typical LF limits of 4.70 and 9.09 MHz on the two ranges in question. My units get very close to, or past, these values before the output

Thank you! I have scanned and uploaded the Ballantine 6126M manual to KO4bb and BAMA. I have an early and late 6125B/C manual that is in the que to be scanned and uploaded...

Fellow Tekkies, You find the darndest things when you're cleaning up. In this case, it was a clean reproduction of the operating and service manuals for the Ballantine Labs 6127B O-Scope calibrator.

Sorry that I haven’t been following this thread closely, so forgive me if you’ve already explicitly verified that the vertical calibration has not been affected. But if the vertical gain is off by

Thank you Toby and Ken for making those measurements. I have several reams of paper on order (28 lb and 32 lb because, as you say, heavier feels better). At the moment I'm using a blue 1/2 inch 3-ring

FWIW, I weighed 10 pages of a Tek 515A manual, I got approx 107 gsm -- approx 405 gsm for the blue covers. Of course heavier always feels better (I would try at least 120 gsm equivalent). --Toby

Hey Grayson, It'd be helpful if you could describe what you've done and seen in some detail. Detailed observations are vastly more likely to produce useful advice than writing up your conclusions.

I suspect horizontal gain drift since that fits the symptoms and I don't know of any other problem. I replace all the electrolytics in the power supply and everywhere else I could find one. Just not

Jared, Thanks, very helpful. -- Michael Lynch Dardanelle, AR

If nothing else, sounds like you need to perform the trace rotation which is a screw trim adjustment which can be accessed from the front panel between the Focus and Readout control knobs just under

When the output falls is the frequency outside the selected range? I have one that will let me set the frequency quite a bit low and high on the selected range but the leveling is not specified

Guys, Apologies in advance if I am doing the wrong thing; I posted this question on the TM500 group a while back, but there seems to be little activity over there, while there is a lot of action here

I have noticed the traceand cursor lines dip down slightly from left to right. They have a slight curve to them. Is there an adjustment that can be made to fix this easily ? The service manual is a

Thanx for that, very helpfull ! René

Hey Bob, chill it with the negativity. Let people use the tools they want to. No one here is worse than the rest. <bob91343@...> wrote:
