We got a great deal on some wickedly hard to find new Tek parts for the 465/475 and 53x/54x scopes, and posted them on the Sphere Stuff Season page in the Tek area: https://www.sphere.bc.ca/test/stuff

Wondering if anyone would care to pass along tips for removal of the larger can capacitors in equipment such as the 400 series power supply section. There are large quantities of solder and seems to t

I'm trying to get in to a 2236 in order to lube or replace a noisy power supply fan, but I can't figure out how to disassemble the pushbutton extensions from the buttons. The service manual says: "2.

I do SMD rework/repair, on occasion. I determined that a reflow oven was frequently required as solder connection quality/failure were not infrequent issues. I built one based on a modified toaster-ov

I recently got a Tektronix 7854 in seemingly great condition from a surplus lot. On it's first power on it functioned absolutely perfect, but now in following uses it has started to be plagued with st

Greetings to the group, hope all of you are doing well, staying positive and testing negative! I'm still going through the estate of a deceased collector of test equipment and recently came across a s

These diodes are historical and quite ancient, so of course they show up in some Tek stuff like spectrum analyzer plugins. From what I understand they have a low Vf, but also a very low reverse breakd

Hello, I recently took an interest in analog computers. I ended up buying two Comdyna GP-6 units, serial numbers 269 and 019. For #269, the available documentation (I spent hours googling and download

Hello good ol' Tek guys. You will please pardon me since this is my first attempt at obtaining help on a group, but here goes: I'm a 70yr old two-way bench tech, started in the tube/vibrator/dynamotor

A simple question, can any 177 test fixture fit into any 577 curve tracer regardless of its build date / serial number? Thanks

Jeff, the resistors connected end to end are an attempt to make a required resistance that was not available as a standard resistor value. Shortage of parts? Engineering change? Select in test? Who kn

I found a small stash of older memory parts, all safely anti-static stored: MK4516N-15 (8) MCM4164BP15 (16) AM9101PC/P2101-2 (2) MBM2147E (1) SMJ4016-20JDM (8) Free to anybody that can use them. Also

My service manual for the Ballantine 1032A scope got lost; hoping someone here might have an electronic copy or could point me to a resource other than a $100 online manual vendor. Thanks, Michael
