Pat, The trace location is under the graticule intensity knob on the left. Likely the contacts are dirty. C1194 and/or C1181 is the one you are talking about with the corroded lead. The first one I

Where is the trace finder typically located on a 453? Anywhere, centered who knows? Dug out the 453 last week and started looking into maybe or hopefully getting it going again. It looks like the X

Interleaved, at least what I can answer Tektronix time mark generators can put out narrow spikes with a sharp leading edge (so you can tell where it is).? They generally have intervals from 1 ns

1) The procedure calls for a Time-Mark Generator. Is this really just a pulse generator? What is the pulse width? 2) Is the Time-Mark a positive pulse, i.e. it does not go below gnd in its low state?

Looks like Ken uploaded it to TekScopes; /g/TekScopes/files/P6021%20Amplifier.pdf George

Yes, there is information on the web that covers it. I haven't done the modification. I just purchased my 2465BDM in 2016 for $100.00 +$53 shipping off of epay. I replaced the Back-up Battery, fixed a

And THAT is exactly how I lucked into this item: the part number was mistyped by the seller and that probably hid it from any other prospective buyers. — Jeff Dutky

I uploaded a Electronic Design idea from a few decades ago for a simple amplifier for the P6021. I haven't built it so I can't attest to it. Ken

Jeff, note it's 067-0625-00. Albert

Jared, Yes, it had occurred to me that adding a couple hundred mV to the battery voltage would require changes to the surrounding resistors to get back to a target voltage that correctly offsets the

If you swap to Alkaline cells, swap R10 and R11 to 200K resistors to bring the adjustment of the trimpots back into a useable range due to the higher cell voltage over the original ones. Also, to

I lucked into a 067-0652-00 Peak to Peak Detector on eBay for much less than the going rate. When it arrived I immediately opened it up and checked the batteries. They read only about 1.25 V, while

This is what I got for these scopes: 4X EEMB ER17335 Nonrechargeable 3.6V Lithium Battery with Tabs Li-SOCL? 2/3A Size 2100mAh High Capacity UL Certified Single-Use 3.6V Lithium Thionyl Chloride

Yep, I'm sure those "customer is also supplier" kinds of situations happen a lot. I read about a company making pulse generators. They used IIRC Motorola transistors in the pulsers, which Moto in turn

That’s hilarious, Bob. Thanks for that part of the story. I hadn’t heard before about returning the gifts! Cheers Tom Sent from my iThing; please forgive the typos and brevity

Roman, I’m seeing somewhat less compared to what you see on the 200 mV DC range. And it varies between plug-ins with one being ~6 mV highest and the lowest being ~2 mV. Of course shorting the input

That's too expensive for me.? It's nothing more than the ring and BNC from a standard tektronix probe with the ID pin shorted to ground.? I need to get around to making one. Harvey

If you are going to use the P6021 with a 7A14 the part number of the adapter is 131-0750-00. There is a guy peddling the adapter in new condition on ePay. The 7A14 can also use the P6019, P6020 and

Steve, You are correct. While working in Denver television at the ripe old age of 18 I worked with RCA TR-3, TR-4 and TR-70 machines and all had built-in video monitors and scopes. The scopes were
