Re: Owon SDS7102 Deep Memory Digital Storage Oscilloscope
Do as old TV show did - YOU control the horizontal - time sweep and vertical - input scale. Does the scope have "trace locator" button? Use it to center a "point " on screen. Does the cope has

Re: TDS744
There's 4 or 5 TO-39 transistors on the CRT neck board. One of them is prone to shorting and causing that problem. Later revisions had a heatsink on it to keep it cooler. Sometimes it will be

Re: Questions about TM mainframes with Option 2
ALL OF THE ABOVE GO INTO 5000 OSCILLOSCOPES AND DO NOT FIT INTO A TM5000 mainframe. There's a compatibility list in the archives here. IIRC, the answer is no.

Re: Parting out 465 (not B) and a 464
The shaft size is 0.125 in or ~3.2mm. I didnt take the 368 back apart but the one i cobbled together in it is the same I'm almost certain. Sorry for the delay in responding. The small dish amplifiers

Re: Dead 7603
Here's what the ripple voltages measured in volts peak to peak: -50V: 20m -15V: 20m +5V: 3 +15V: 20m +50V: 10m +130V: 0.2 So, all out of spec except for +130V, and +5V way out. +5V was a high duty

Re: Owon SDS7102 Deep Memory Digital Storage Oscilloscope
Sounds like you have enough scope for the moment. You should use the probes. You have an electrical graph. The Y axis (vertical) is almost always the voltage. The X axis (horizontal) is almost always

Re: Dead 7603
Thanks, everybody, for your help. Here's where I am now: Primary not open; it measures about 3 ohms with the on/off switch on (obviously open with it off!). Poked around P1171 and measured DC

Re: MEDIA MAIL (Re: [TekScopes] I have two Tek manuals I don't think I need)
David, they absolutely don't want to offer it. I just mailed a book (a user guide for a camera) to a friend. The counter agent was funny. I handed the package over and said "it's a book and it should

Re: SC504 Gain Knob Removal
Hi Larry, Your question got me wondering about this, so I took the side cover off of an SC504 to have a look. The service manual mechanical parts diagram shows the knob has a longer part that goes

Re: Questions about TM mainframes with Option 2
You have some conflicting terms. The 5Axx modules are 5000 series oscilloscope amplifier plugins. They are not compatible with the TM500/TM5000 series mainframes. The AM502 is a TM500 plugin. It is

Questions about TM mainframes with Option 2
Hi all, first post here. I'm looking to set up a TM 5000 series mainframe and trying to sort out the compatibility gotchas before I "pull the trigger" on one of these. My main interest is in the

Re: 114xx bezzel buttons
Not sure exactly what your question is, but I've removed the panel/trim from several 1140x's to gain access to the crt, using the procedure in the service manual on Tek's website, and I don't recall

Re: DC 508
The option 7 on the DC508 increases its value as it allows it to work with the TM500 series tracking generators. If it has option 1, the oven oscillator, that also increases the value. The oven
