This morning, I was working with my scope, and I touched the CH1 BNC socket - ground side. BZZZZ. I thought I was dreaming. I measured the voltage to AC Ground - 113VAC!!! So something's leaking

Alex, There is a vast amount of information around about the A5 corrosion problem. The corrosion usually causes two 10k precision resistors to change their value. These set the voltage reference for

That's a excellent tip for removing SMD caps, thanks for sharing.

OK - the correct physical size is 1/3 AA. Although tagged batteries of that size are available, they all seem to be rechargeable 1.2V. But, the physically smaller 1/3 N (11.6mm dia, 10.8mm long) at

That is really neat! Apparently available in Australia and NZ. But so far no luck finding in the UK or Europe. I'll try out my solution and report back what the result is. Craig

Hello Craig I've recently had to replace the original 1.35v mercury batteries in my 067-0625-00. I used 1.5v alkaline A1PX-BP1 batteries. Readily available and they are an exact fit - but you do

Wow- my G is s/s 9934, so it's just after the change.? Strange that they didn't change the sheet metal right away. -Dave To: [email protected] Sent: Thursday, October 25, 2018 12:44 PM

I have two of these. The batteries are used for is to provide a DC offset "bucking voltage" of 0.3V via a resistor network and adjustable resistors R8/R9 that sets zero output at 1.2V p-p. If

Alex, Very nice cleanup job. I'd just like to jump in here about removing SMD caps with minimal chance of pad damage. Every technician has his own favorite method of removing SMD capacitors. My

This is a 2465B Sn 55K purchased off ebay, very good external cosmetics, almost pristine interior with only very few traces of dust and so far have not seen any signs of having been disturbed or

Anyone had to locate replacement batteries for this unit. Only marking on the battery is 1A. Original Tektronix description is: 1.5V, 650MAH, Alkaline-Manganese Dioxide Tektronix 067-0625-00 Peak to

Thanks for all the replies. The one in this link https://www.surplussales.com/Variables/Ceramic/CerCap3.html posted by Gary looks amazingly close. I'm going to see what else they have and make an

No issues to be expected at the frequencies involved. Any good-quality trimmer should do but you may prefer the looks and fit of an original...... As promised, I'll have a look on Tuesday but please,

I recently bought one of these assortments to get several different values for a project. I haven't used any of them, so

I was partly wrong. Tek retooled the front panel for BNC, but not until 1967. From 1963 through 1966, they used the UHF front panel with a square-flange BNC jack and plastic trim covering the

My 535A and G are Guernsey-built. The 535A is s/n 101936, and the G is s/n 101127. They both have BNCs which look like they were factory-fitted, though they are of the special Tek type with enlarged

Just realized yours is a 468. It's probably the same as the equivalent cap in a 465(B). I'll be in the lab coming Tuesday and have a look, possibly take a few pictures. I can't imagine the

The cap is C120 on the A13 board so its A13C120. Thanks for looking.
