I've had this instrument for several years; it gets occasional use, and had probably run for under 10 hours when I bought it. Yesterday on power-up there was no trace. I opened it up for the first tim

Hi all, I haven't been here for quite a while but have to post to let you know that I am ready to let some of my test gear, including Tek equipment, go to someone offering a good home, FREE. The catch

HI, I acquired a very nice Tektronix 465B for approx US $ 30.- The serial is #701524, so it is a local Dutch TEK 465B (the factory was in located at Heerenveen, NL, some 40 Miles distant from my Home)

I recently acquired a 577 Curve Tracer with a Type 177 test fixture in pretty decent cosmetic shape except for the Current/Div knob on the 177. The knob is part number 366-1433-01 (they changed the kn

Does anyone here have experience download PNG or BMP screenshots, using VISA-COM (globmgr.dll) in VB6 from their TDS series scope (or other tek scopes i.e, MSO4104)? I know how to setup the screen sho

I've been having a grand old time here, going thru my collection of 3-series plugins, and checking all the input attenuator compensations. I know that they don't normally need any attention, but these

Hi all. I'm looking for a TDS210 or TDS220 motherboard in any condition, working or not. The cheaper the better as I'll be stripping it down to hopefully reverse engineer into a schematic. If anyone h

On this 475 of mine, AUTO sweep stops working after a while... no sweep at all, spot stays on left (vert amp OK) - this happens only after a few minutes warmup; just after power on, AUTO sweep is fine

i have a nice 465 that has busted vols/div knobs,does anyone know if replacements are available anywhere,the grey bodys are missing on mine,they still work fine but with those replaced it would be min

I've created a new folder called "TM500x Rails". In there are STL files, as well as the Sketchup 2017 file for replacement guide rails for the TM500x mainframes. This is the black rail on the bottom.

Hi all I'm trying all possible resources to source this. I need a replacement LOGIC-A PCB, and/or the PROM which is socketed on that PCB. If anyone has a non-working unit, and is willing to part out t

Hi Does anyone know if there are adapters for 3-pin SMD transistors to suit a TO-92 mounting? Most of the older TO-92's are NLA from the reputable suppliers, and I was thinking that about soldering a

Hi All, After repairing the reference section I realised that component replacement around the DAC may require re-calibration. Reading the entire process I realised the calibration process is daunting

Greetings! Does anyone work on 2000 series scopes? This 2024C apparently got wet at some point in time. There is some obvious corrosion on some of the boards. The unit does not turn on at all. I need

Hi, I have an opportunity to acquire a Fluke 80-6 (6kV) probe. The HV for my 7603 scopes is 12kV, but the Test Point is approx 3kV. Is the 6kV probe sufficient to safely probe, or do I need to wait fo

I bought a 321 yesterday that works. That "works" is only it comes on with a sweep. No other testing has been done yet. I know this uses Ge transistors. Which ones should be changed due to whiskers, o

Hi everyone- I am hoping someone may be able to assist in fixing the DC-DC converter of this cute scope. I recently acquired a Tek 422 AC/DC that has ps issues. The history is it was supposedly workin

Hi Forum, I have sucessfully re-capped my 2445 Tek scope, but unfortunately I broke the axial coil/inductors that connects A1 to the CRT. (these were extremly brittle..) The inductor reads "0327" and

Good day folks, I have a new to me 7CT1N curve tracer and have a question about how to set it up. What kind of cable is used to couple the tracer's output to a vertical amplifier? I don't recognize th
