Jean-Paul - It is a far-too-frequent error. The patented precision track plating and wiper button design make the Variac significantly better than other brands that I have used. If you have not seen

Does this procedure also apply to 2465 ? thanks. maurizio

Okay... but, where? -- Roy Thistle

John, Thanks for the information. I had not had the CRT problem - yet. There's always plenty of time for additional problems to accrue! Not to be snarky, but did your filament transformer have

Chuck Harris is the Tektronix HV transformers guru, on tekscopes2 only, due to,issues with tekscopes moderators Ask Chuck, he may have tips but procedures is difficult and needs correct wire,

Hi. I might have one of these. I will check.

Hi. I also have two 310A scopes. Both have had power transformer problems. On one the crt heater winding broke down and I had to add a small filament transformer for the crt filament. On the second

I have two 310A 'scopes that were, if infrequently used, behaving pretty well until, quite suddenly, the one made in around 1963 (S/N 019006) had lost its -150 supply, which incapacitated it.

Hi: One of the former members (former member AFAIK) used to rewind some of the 500 series transformers. He is now? on Tekscopes2. Don't know if he is doing it anymore. There is also a litany of

Hi, Anyone rewinding these? My 561 lost its beam... Thanks

Whether you decide to replace the battery now or not, take a few minutes to back up your calibration data first. Two easy methods: 1) Use the built-in diagnostic routine EXER 02 and record a video

My 2467 battery has a '97 date code, still going strong. I have the gear to calibrate it when it gives up, though. [email protected]> wrote:

We use the date code imprinted on the batteries Over 5-10 years old, replace regardless of voltage J

Jean-Paul - A Staco is not a "Variac," which is a registered trademark. The original Variacs were the variable autotransformers made by General Radio Company. The current holder of the trademark is

David and Dale: YES on all: As we were power elecronics designers since 70s' we have a collection of Variacs, the best are indeed the old Staco and GenRad with ACV RMS and AC . Mains in UK EU =

I suspect that he means one of the portable Variacs supplied cased with an output voltmeter, such as the Type W8MT3VM. For field use I built my own portable cased Variac with an output voltmeter and

Voltage is a poor indicator of remaining charge, lithium batteries maintain a mostly flat voltage over their life with a sharp drop at the end.

I am working on a Tektronix 2467 oscilloscope and need to know if I need to put new 3.7 volt battery in this oscilloscope when to battery reads 3.7 volts.
