Thanks everyone for the endorsements on these component suppliers. Makes me feel good about joining in, and you have given me some good ideas on how to order - like accumulating a shopping list and ordering when it's over a certain value.
Ke-Fong, you bring up a point that was on the edge of my mind last night: this 465 scope C1419 cap is clearly a marginal element of these scopes. Why would they do that? Because, as I well know being in the R&D branch of tech development: cost, cost, cost. Sometimes you don't know where the marginality in a design is until you get it in the field. And mass manufactures have to get each and every component down to the lowest possible cost. Given the serial numbers on these things it's clear Tektronix made well over 300,000 of them. That's a lot of C1419s. And that's just one component in the whole scope.
I guess I'm not a restoration purist in taking on 465 repair. I'm very willing to use modern components in place of originals. Especially when a marginality like this has been exposed by several lifetimes worth of use in the field. I hope I'm not offending any enthusiasts with my intent to apply an overkill upgrade on this cap. But it seems reasonable to me. And it's part of the hobbyist entertainment to over analyze and over think such minutia. But that's what engineering is, no?
I'm liking the Nichicon UCY2C470MPD1TD for this cap. I'll probably get 10 of them from Mouser. I'll even replace it in my working 465 once I have this one up and running. Seems a good prophylactic. But I won't be ordering it for a while. I have a lot of scope to go through before I know for sure everything I'll need. And I need to go down and make sure it'll fit too.
