Repair broken Tek 485 or buy good used 2465/A/B?
IMO,the 485 is much worse than a 2465,having lots of flaky attenuator
problems,a bitch of a power supply repair-wise,and less accuracy than the
2465 series.And you get a better CRT display with the 2465.
The 2465 was the best portable scope TEK ever made.What killed it was TEK
selling off the ICO/Hybrid plant to Maxim,and Maxim cutting TEK's throat
by forcing a last-time buy on TEK-made ICs.
The 485s are getting really old,the HF switch contacts are degrading and
unavailable.
The 2465 is more serviceable -if you can get the parts.
the 485 has the same problem.
What about the 2245, 2247?
