[R-390] re: R-388 caps (OT)

[wli]

How durable the *dogbone* ceramic capacitors in the R-388/URR? They are widely employed as bypass caps... like .01µF everywhere it seems. How were they made?

Do they deteriorate like the paper caps of that era? My impression is no. But I do not really have any experience with this type of capacitor.

In contrast, I have seen many leaky *Black Beauties* in other receivers I have restored, and have replaced them with Orange Drops or other modern caps.

Thanks
