Tektronix oscilloscope 2445 DMM 4ch 150MHz 1985 repair teadown

Another top class fantastic Tektronix Oscilloscope, the 2445 exist in a normal and a DMM Digital Multi Meter version, I found a few leaked caps in the powersupply and the more classic RIFA caps, normally this line of scopes have 4 RIFA caps you must replace, but this is a late model from 1985 so they improved at bit and have only 2 RIFA caps left in it. Weight is 12-6kg, it use 81 watts at 225 V AC 50Hz Bandwidth measured to exactly 150MHz -3dB this one got the 01 and 06 options installed, I used 6 x 220uF 63 switchmode grade caps for the powersupply. I am super happy this one works perfectly fine now, and i am also impressed with the DMM design, features accuracy and resolution, A little bit surprised to see LM399 as refferance voltage, wow that is the good stuff. -- #oscilloscope #tektronix #repair -- I use auto generated subs, i am sorry there are a few spelling errors, maybe one day they can do it better.. -- (Thanks to all my Sponsors / Traders / Swappers / Sellers / Buyers, without your support and constant flow of cool items in/out, none of this would be possible)
