Brüel & Kjær 2308 XY Recorder Plotter test repair teardown

super nice Brüel & Kjær unit from about 1985, X amplifier board was defective, it was -15V and +15V supply, both transistors fried, dropped that idea and used 7815 and 7915, now it works.. so now i can perform mecanical XY curve plots like a pro, like they did in 1985. -- when you are done with this video, PLEASE try scroll thru my other videos here    / @teardownoz2cpu   -- #teardown #test #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)
