At this point, even though given the cleanliness of the scope, I'm leaning towards returning it as something doesn't feel right.
I really wish I would have jumped on the other one, but it was gone. One other thing I didn't mention, but which bothered me, was the fact that when I was taking the scope to my shop in the basement, and carrying it by the handle, it seemed like the guts were moving around inside the case, almost as if a rear bracket wasn't secured, etc. I picked my 465b up and carried it in the same way, and it was solid.
I asked a question about this, and the seller finally replied, 3 days later: Remove the rear cover 6 screws and fix what is loose. Nothing should be moving around.
Here is the description on the one I should have bought:
Offered here is a Tektronix model 2465A 350MHz 4 channel analog scope. This instrument has no options.
With so much hype surrounding the Tek 24xx scopes, I will be succinct:
I buy, sell and repair electronic test equipment for a living, and have for decades. I have worked on hundreds of scopes, and have all the calibration equipment service this model for some of the largest repair facilities in the country.
This scope has had the power supply serviced with all small electrolytic capacitors replaced with high quality Nichicon 105c parts. A complete adjustment was performed using Tek factory equipment.
This instrument didn't need any other repairs.
This scope looks great and works perfectly, guaranteed.
And the one I bought:
For sale is a FINE working Tektronix 2465A 350Mhz Oscilloscope.
Real nice condition and works great.
Comes with power cord and cd with operating and service manuals.
Cleaned, repaired and tested for proper operation.
No start up errors.
No physical damage to case or knobs.
This item will be well packaged.
