Be warned, IIRC the linkage that connects between the front panel knobs and the spindles on the HV box must be electrically insulating. You so don't want 1kV on the front panel knobs! David

I've just checked my spares unit, and it is also missing the dual knobs! Craig

Thank you Roger. I will try these out over the next couple nights and report back. Much appreciated. Dave

Does anyone have the winding data for the 561 HV transformer? The manual shows it to be Tektronix part 120-225. thanks

Rick, I cannot help with the first item. Speaking to the second item. The offset pot is held by a plastic cup which is affixed behind the knobs of the pot. This plastic part is not available, except

hi, Does anyone know about the following mechanical bits on 576 CT front panel ? a) Max Peak Volt / Series Resistor linkage mechanism: I am missing the dual knobs for this & the mechanical (coaxial ?)

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
