content: Yes, I know, it has those evil hybrid IC, once this bugger acting up, the scope will turned into oversized door stop, but its just so tempting.Fully working, no probe nor any other accessories,physical inspection and brief testing on site are allowed.

content: Quote from: dr.diesel on December 22, 2013, 02:57:08 pmThanks, I sort of get it though, its just I'm wondering if its still not highly desirable, why the price is still relatively high say compared to old Tek 465.

content: QuoteLooking through sold oscilloscopes the 465 and TAS 465 fetch pretty similar prices - the average for the TAS465 does look a bit higher but there is a considerable overlap.The problem with the later 'scope is that it's old enough (mid 1990's design) to be completely out of support by Tek but the "service manual" doesn't have component level schematics. It's also SMD with components that are difficult for many hobbyists to solder, and with quite a few tek-specific custom chips (now unobtainable). Finally I suspect that nowhere near as many were produced as 465's so trhe availability of units to act as a source of parts is lower.The 465 'scope has easily obtainable schematics and apart from a few problem components such as tunnel diodes is built from mostly available stuff.Consequently if you buy a TAS465 and it dies that's probably game over whereas you'll have a decent chance of repairing a 465.On the up side the TAS465 is a more modern 'scope with more features than the 465 - especially on-screen display and cursor based measurements, hence the slightly higer price overall.

content: The price is also highly variable - 6 months ago they were averaging AU$200 on ebay, 6-8 weeks ago it was ~AU$250, this week it's more like the AU$175 Dave quoted.And yeah, for an early 'analogue with some digital features' (cursor-based freq / time / voltage, etc.) scope, the menu doesn't completely suck and the autoset button works reasonably well.

content: Well I have a TAS485 the 200MHz big brother to the TAS465. One advantage this scope has is all four channels have 2mV-5V full attenuator range. IIRC the TAS465 is the same but it's 2 channels.Still a nice analog scope with digital measurement.SamW3OHM

content: No keeping it, it replaces my Farnell 20 MHz scope with it's cursors and all the other goodness from Tektronix on the screen, its digital counterpart is a Siglent 1102 cnl another 100mhz scope.
