Ben, thank you. I have printed out your sworn statement for my wife’s

review and anticipated favorable response.

Neil, this approach should work very well for some of the condensers

in the SCR-183/283/ RU receiver, especially because the inards are

being discarded. Very amazing is this approach with the crystal filter
assemblies.

I have seen “a large soldering iron” often mentioned for resealing

metal condensers such as for those in the ARC-5 type receivers.

But, I do not remember ever reading a suggested wattage.



Last week my Dad  gave me an old, no name 200 watt soldering iron.

Do you remember typical wattages for those you’ve seen?

I went to American Beauty’s website. Good grief, their prices and

wattages were all over the place.
