Re: A sick 465B


 

Mark,

Thank you for the detailed list of replacement parts.

I am working my way through repairs to this scope (I have a list with at least ten entries, including recapping the power supply and replacing the CRT), and the work is going a bit slowly (partly due to other projects unexpectedly demanding the bench). The new CRT will be arriving today, so I think I should address the beam intensity issue soonest, so I can verify that the new CRT is in good order. To that and, I would like to check the 22M resistor that you said may have gone high in the CRT circuit. Is the resistor in question R4124? If so, is there a good reason to not simply replace that with a common metal or carbon film resistor?
