That's awesome job you did. I own one of these beauties and reading your post I decided to clean my tektronix 465. But, when I tried to remove the front panel I just couldn't remove the push buttom for 20BW limit, and also the delay time position knob and the time scale knob.
Can you show me the way?
Also, I bought my scope with some leds burned out or missing. The power led and the triggering leds are missing (are they incandescent lamps? Can I just solder a led on the board?) - Finally those leds from ch1 and ch2 rotary switch aren't glowing. Those I did't reach yet. Are they easy to be replaced?
Thanks a lot for you post and any help you can give me.
