Hi Bill: A fair offer where? (Some said 150.00... but... is that USD?... I assume it is.. but, assumptions often make of me something I don't want to be!) Best regards and wishes. Roy

Hi, Remove, clean an reseat the hybrid circuits. Look at the details in the extended diagnostics. If it is one channel that fails, you can swap the ICs to find if any of them id bad. Although I'm not

Thanks Matthew 73 Richard W4MCD

I have 11 of them (if not more) in my library. I am looking at "103 Projects for the Electronics Experimenters", by TAB BOOKS Inc, Blue Ridge Summit, PA 17212, first edition June 1981. Other include

Hi all,I am new in this forum and I hope that I can find a solution to my problem.I have a 2782  spectrum analyzer whom the focus, astigmatism and intensity are not operating at all.I have the 2782

I recently picked up a Tektronix 2430A for next to nothing because it had failures on the self test. Most of these failures were caused by a dead backup battery. I found a suitable replacement and

i own 4 2235A and the military version as well and they are a great analog scope. Mine came off Ebay after negotiating each one. i won't go above $200 on them myself. I did pay 400 for a brand new

Hello: I received 3 P6131 probes for the cost of shipping. The problem is the probes came with the collar but no ground lead. I need: 1) 3 Ground leads that connects to the collar. 2) 3 probe tips

I would guess $100 to $150 but for myself, I would hold out for a 2232. The 2232 does a lot more for about the same space and cost.  Bert >

All, Update on the group purchase. As of this morning, we have deposits for 7 kits, plus I'm planning to order 2 for my own use, making 9 total. To avoid spamming the list with daily status updates,

In my search for an Oscilloscope I ran across a local 2235A in excellent cosmetic condition and it produces a signal on both channels. Looks like it had a very easy life. Doesn't even have

First question: are all the CRT voltages about right? Second question: are the "low voltage" z-modulation waveforms correct? It is simpler to inspect grid waveforms if you have a suitable probe,

I powered up a 485 that had been sitting on the shelf for awhile, finding it completely dead. It was working nicely prior to that. After replacing a pair of famous tantalum caps it powered up but no

Roy, thank you for the information I appreciate it 73 Richard W4MCD

I've seen bad capacitors in the Low Voltage Power Supply cause a slow startup. I would say that's usually the main cause especially in this model since it will not have the surface mount capacitor

Hello, on my bench: LeCroy 9354AM as main scope, Danaher TDS754D as second. IMHO, the TDS754_D_ is the best of the old TDS gaggle. Unlike the A / B / C, it has intensity grading in the DPO view.

I’m getting ready to purchase this scope from eBay. The add says it’s slow to startup and assumes it has problems. I won’t know until I get it tomorrow or in a few days if it’s the delayed

I'd say 1/4 to 1/2 watt with the provisions that the original (given the date) would be 1/2 watt.  Considering that you're shorting plate leads together (or the equivalent in a later scope of

I have a TDS694C that works perfectly in every way as far as I can tell, however under calibration, the signal path check reads fail. Is there anything to do for that? Jerry yahoo.com@groups.io>
