Kerry Wong decided to take a look inside an old Tektronix 2213 and share his findings.
I love old Tektronix analog oscilloscopes and I could not seem get enough of them. So when I saw a cheap “untested, unknown working condition” Tektronix 2213 listed on eBay recently, I just could not resist the temptation to grab it.
Unlike the Tektronix 2445 I got earlier, Tektronix 2213 is a no-frills basic 2 channel 60MHz bandwidth scope with limited delayed time base capability, and thus is pretty easy to service.
