content: Looking to get an analog scope and 2 are up on my local craigslistA tektronix 475 or a tektronix 2336yaThe 475:http://www.testequipmentdepot.com/usedequipment/tektronix/oscilloscopes/tek465seriesspecs.htmThe 2336ya:http://www.testequipmentdepot.com/usedequipment/tektronix/oscilloscopes/tek2336.htmSo which would be a better buy? Seems that that the 400 series while older is a very popular series.The 2336 is a bit cheaper than the 475 but has less bandwidth and no probes included. It is a smaller and lighter and a bit newer.S any thought on which one I might want.

content: I have never used 2236 but I like my 475A very much. Servicing newer scopes is generally harder, too.

content: I would take the 2336... so much lighter and smaller, and easier to repair also.

content: id chose the 475, if only because i dont like the permanently attached cover swinging down and having controls in it. double the bandwidth is another plus.

content: If I was making the choice I'd pick the 475. The 2336's cover would be very annoying; I also feel it would be harder to work on over the 475. I can see the appeal of the small scope if space is limited though. If space is a consideration maybe it's time to think about a LCD based scope like a TDS210, etc etc..

content: 475! You won't regret it! I have a 465B and I was surprised at how small it actually is. The 2336 just looks like a cheaper plastic-ier 465.

content: I would take the 475... again.As you can see it is really small (left 475, right top 2215A).But of course these are over 30 years old now. It depends of the conditon of the 475. You might consider to go for a newer one. The 2336 is not much younger (and I wouldn't like the swing down cover too).The 475 has nice display illumination, but I prefer the brighter display of my 2215A (which has only 60MHz but some nice features as seperate brightness for A and B sweep and trace separation).If you can, try both out, watch videos of them beeing used or wait for other offers. You also need a little luck to get a good one.Dave has two videos of the 2225 and this looks ok too .EDIT:Have an emc mesh filter in front of the 475 display, this is why it's so dark.And yes I agree, the 465B is also very niceand would be a good option.

content: I had a 2337, it's a fine scope but viewing area of the CRT is not as great as the 475.Why a 475 and not a 465 or 465B?Do you really need 200Mhz bandwith?Probes above 100Mhz are very expensive, and i often see people using 100Mhz probes with a 200 of 275Mhz bandwith scope...This is nonsense.I think 100Mhz CRT are better focus than 200Mhz ones.The 200Mhz are distributed plates technology, not the best focus possible.I would choose a 465B.Not to be forgotten: the HP1740A 100Mhz, that is also a very good analog scope.

content: Quote from: edavid on November 23, 2013, 05:25:53 amI'm curious about this (and I do apologize for the thread hijack), but in other threads here, many people have said to stay away from the 23xx line of Tek scopes. My wife bought me a 2335 for my birthday that has no trace. The plan is to fix it and use it, but all of the other threads somewhat discouraged me from bothering. I did, however, find the schematics and plan on fixing it anyway.

content: Derrick, go for it. I picked up a 2235 from a hamfest for $40. It displayed a vertical line. A good cleaning of all the switches and the vertical, horizontal amplifier controls and the time base control resurrected the scope. Have fun with it.

content: Well after wait awhile (month) the guy came down on the 2336 $100.00 from 150. So I got itPicture on top of the project tds360 for size comparison. Its small I like it. Need to order some probes . The tds360 was cheap 200mhz and 1 gig/s each channel but only 1K sample memory and will not trigger on channel 2.Will do mini teardown.
