Emile Posted January 2, 2020 Share Posted January 2, 2020 Hi, Haven't used an oscilloscope for 40 years ... and don't remember how But, think (haha ) that they might be useful for some troubleshooting. Found a Kikusui COS5040 40Hz oscilloscope at a local college for very little money ($50). Just not sure if 40Hz is useful ... Appreciate any advise. Thanks, Emile Quote Link to comment Share on other sites More sharing options...
WMcD Posted January 2, 2020 Share Posted January 2, 2020 40 kHz MHz probably. [edit] I would say that there are plenty of units run by PComputers which will do audio range stuff and have the capacity to store and print waveforms and FFT. Granted they are going to be about 3x what you're talking about. WMcD 1 1 Quote Link to comment Share on other sites More sharing options...

Dave1290 Posted January 2, 2020 Share Posted January 2, 2020 Maybe you could work a deal with Carl on the Luxman in trade? 1 Quote Link to comment Share on other sites More sharing options...
Emile Posted January 2, 2020 Author Share Posted January 2, 2020 Haha ... @carlthess40 ... Carl, how about a very nice Yamaha CR-620 for an oscilloscope? 1 Quote Link to comment Share on other sites More sharing options...

So, holding off for now Yeah, don't buy a broken oscilloscope. You can do quite a bit of troubleshooting with a multimeter of some sort or a VOM. The scopes colleges usually flog are older models, and one should pay attention to calibration dates. If you are actually interested, talk to the right people, or go to some ham fests if they have them in your area. There is a chance you may find a better scope...you may have to pay a little more, but you'll probably do better than an off brand 4 meg scope. I have a B&K 10mHz scope I bought for 40 dollars years ago, and have been wanting to upgrade. A local retired friend hits the ham fests, so when he seen a Tektronix 2246 for 100 bucks in perfect working order, he couldn't pass it up. He has his share of oscilloscopes, so he passed it on to me for 100 bucks. 3 Quote Link to comment Share on other sites More sharing options...
carlthess40 Posted January 2, 2020 Share Posted January 2, 2020 Emile, give me a call. We can work something outSent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted January 2, 2020 Share Posted January 2, 2020 About 3 years ago I bought 8 Tektronix tube O scopes that had been sitting in a barn for years. Got them all at an auction for 10 bucks. Opened them up and robbed all of the Amperex and Mullard tubes that were inside, and then a friend of mine got all of the beautiful tube sockets and other parts. All that was left were the chassis, which we recycled..... 1 Quote Link to comment Share on other sites More sharing options...
Chris A Posted January 2, 2020 Share Posted January 2, 2020 TrueRTA (freeware) has an oscilloscope mode (which I've never had to use). Unless you just want to play with a hardware oscilloscope for things other than audio, I'd recommend TrueRTA instead. Chris 2 Quote Link to comment Share on other sites More sharing options...

JohnA Posted January 3, 2020 Share Posted January 3, 2020 Why would you futz around with an old broke scope? https://www.amazon.com/Oscilloscope-Multimeter-LIUMY-Professional-Scopemeter/dp/B071F1H3PG https://www.sbsbattery.com/sbs-700-oscilloscope-multimeter.html 1 Quote Link to comment Share on other sites More sharing options...
