FYI Had an issue with a recently acquired 3A6 - trace switching multivibrator was inop. Contact cleaning and reseating the transistors did the trick. The interesting part was that both transistors had

Other than cooling (ie ensuring that the fan intake is not obscured), and ensuring that the fan does not do a good job of vacuum cleaning the floor and depositing it in the scope, I can think of no

Hello all. Are there any known problems with using a 535A in vertical position, i.e. with the fan at the rear looking down and the front panel looking up ? -- Andr??? Majorel

Hello David, I'm fairly sure that all the original TDS520/540/620/640/820 series do not have battery backed real-time clocks. The time is kept in non-volatile memory but not updated while powered

Hello, Of the two choices, the 7904 would be better for most work. If rack mount is required, then it going to be a R7xxx, with three slots. The 7xxx mainframe choice depends more on what one is

Hello again, I think I goofed yesterday and replied to the moderator instead of the list. I just wanted to clarify the trade offer. The 7S12 is just the 7S12, no plugins. Also, the knob for turning

I have a 2465A, when I connect a prob to the built in calibrator, the timebase and volts/div only have slight effect on waveform by switching through the various settings, as I increase the timebase

For the benefit of the list archive: I checked the bezels on my 310A and 360 and found that they are slightly different, but they are mechanically interchangeable. The 360 bezel is a bit more solid

Gentlemen, I have a user's manual for the CSA803 Communications Signal Analyzer. If anybody wants this, they can have it. -kurt

My 7904 is my general scope of choice. In fact it gets used most (currently housing a 7L5 and tracking gen), with a 475/DM44 as an easily luggable alternative when needed. Unless you need rack

I'm looking for a new toy and am thinking about a 7904 or R7903. There is a lot of material in the archives but I would still like to get some ideas from the group as if this is a good choice or if

- Before tearing into everything, I would start out by putting the scope into X / Y mode, ( make certain that the intensity is turned down), and checking that the spot can be positioned all over the
