Gday! I've acquired a Tektronix 2212 with a good EHT and CRT. It had an unstable PSU i tracked down to bad solder on the main trafo last night and after finding that i decided to reflow the solder everywhere along the way checking the caps (out of circuit) and found two 15uF 16v electrolytic caps to be bad on the memory/computer board. could i replace these with film or polymer or should i use Lytics again? Thanks!

You must have a sad, sad boring life if you hate on people harmlessly enjoying life with an animal costume.
Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Re: Tektronix 2212 bad 15uF caps
whatever, its not going to be running 20+ hours a day like a pc or monitor.

i would suggest to use polymer if you can find themComment

Re: Tektronix 2212 bad 15uF caps
Thanks STJ, took your advice since they were going to the ground plane anyway i decided to replace them with 22uF.
decoupling?
Either way, it's not in the signal path...
Works great now!!
It was surprising to find one with a good EHT module and no Horiz. problems for so cheap! The RIFA filter caps on the primary were leaking the famous brown goo though... https://www.badcaps.net/forum/showthread.php?t=32262Things I've fixed: anything from semis to crappy Chinese $2 radios, and now an IoT Dildo....

Re: Tektronix 2212 bad 15uF caps
From what I have seen elsewhere, 15uF 16V seems like low leakage or tantalum units - given the age of the unit, were the defective units in cylindrical cans?My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment
