I picked up a Tektronix 545B last year for $50. A lady elecroinc engineer had it laying around for years but said it still worked the last time she used it. Unfortunately she was missing the power cord.
I want to learn how to use it but want to first know if this was a smart purchase given that it works properly?
I want to be able use it to diagnose or check my tube amps (Dynaco MKIII's) when I decide to rebuild them. Will this do the job?
Thanks
Jay
