Hi Randolph, You checked all the tubes, but also the voltage reference tube V609? Should measure about 85 V. The grid voltages of V 624 should be approximately equal, well within 1 V or so. The

Chuck, The only use of the linesman glove was to put the HT anode lead somewhere that would hold it from moving, and to keep it away from me. I never implied to wear them while working in electronics,

Mine has it and it's documented in the 11801 user and service manuals. The user reference manual on p 42 says: "The signal from the calibrator output is a 250 mV square wave with a rise time of

Thank you for sharing your experiences!

Apologies for the delay in updating, was a bit under the weather. Months ago I initially used a 5x mag lens to investigate the solder joints in the PS areas. Didn't see any issues. Last week when I

Hi Randolph, There is no reason to expect the plugin would pull the voltages off their mark. Get the -150V right and everything else should fall into line. -Chuck Harris randolphbeebe@... wrote:

Thanks Roy, My 585A does not have the black beauties but the red Erie caps that tested good in circuit. I replaced them all anyway this morning just in case there was cumulative leakage problems. No

Hi Chuck, The scope has a CA plug-in right now with a type 81A adapter. I am pretty sure all is good with the plug-in because the scope responds to the vertical position and input etc. I have a couple

Hi Dennis, What I found in an accurate dimension for the probes is the diameter of the metal on the removable (replaceable) probe tip. Example - the P6137 (p/n 206-0378-00) is an accurate 3.5mm

The full set of Tektronix catalogs are available in PDF form online at the TekWiki and other sites http://www.w140.com/tekwiki/wiki/Tektronix_Catalogs They are very useful for determining specs,

I found a P6406 last night. Thanks to everyone who replied. - Bill

Hi, Perchance a Probewiki on the Tekwiki page? larry

Hi Dennis. I don't have a catalog to see the probe pages you refer to in the last line in your post. By any chance could you please add them as a downable file? I have multiple probes and this would

The charging and discharging currents for the timing capacitor have to pass through the switching circuitry of S155 so bad contacts there will stop the triangle generator working and the other

Reg, If you are out for exotic toys, try finding 1180x or CSA803x with fast calibrator. You can tell it apart visually by the calibrator jack being gold 3.5mm type instead of Nickel plated SMA. It's

Well - I did take some pictures.They can be seen here (scroll down): http://snyders.site/Pages/Electronics_2016.html The winding "machine" is built on a quite heavy brass plate Cheers Ulf Kylenfall

7934? That's like asking a cupcake baker to whip up a 20 layer wedding cake... I envision one 7934 tranny as taking a couple of days to make. -Chuck Harris Kyle Rhodes wrote:

Hi Greg, Yes, for many years it was not clear what Tek was doing with their probes. I think the 3.5mm and 2.5mm probes were an attempt to make it clear from their description how big the probe
