Dale, Mia culpa on the TM faux pas.... As an inventor and having fought many patent infringement cases, I am red,faced... Thé Staco (tm) are robust and great workbench units. The GenRad have

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.

Thanks @Jean-Paul. What do you mean by "metered" variac. I have a variac. Do you just mean put a meter on it to more carefully calibrate the suggested voltage? Or, if I read-between the lines, where

thank you !

Hello Rafael, Sorry for my late response. I honestly don't know if this works on a TDS620A. I do not have any schematics of the TDS620A but if there are some configuration-resistors on the

I have been a fairly quiet member here for a few years. Electronics has been a hobby my entire life and has been joined at the hip with my business for 33 years. Unfortunately I must close my business

Hi Mike, I don't see your direct email address so I can't respond off list. Qservice web page is: https://www.qservice.tv/ I'm a satisfied customer. Regards, Ignacio -- Este correo

hipping 577/576 is always risky, sellers seldom have the correct box thickness stregnth or packing materials. Most arrive with broken or internal damaged CRT. Take photos and keep packaging, sned

Interesting that this probe to BNC adaptor is not yet listed on TekWiki. The picture looked a lot like one of the standard #6-32 probe to BNC adaptors (013-0054-00) of which there are two sitting on

I'd choose my own selection over some other random internet person every time. Too many self proclaimed experts appear on a whole range of subjects, then many sheep start to follow and believe.

Hi Michael Could you tell me which pot you are refering to? I also have the problem of the horizontal size of the sweep not going fully to the left. thanks

This is correct. The adapter might be used for other P51xx series probes? but I have a few P5102 probes for my THS700 series scopes and would like to get everything all adjusted and straightened

Jim, This is not your “typical” probe to BNC adapter. It is used for the P5102 (1kV), which I presume is what Jared has. I don’t know where else it might be used. For those who have not seen it,
