Hi Guys,

I've been reading with interest the discussion about recapping and the 
use of 'Orange Drops'. I bought a bunch of the 716 series from AE a 
while ago (enough to do a full recap on one R-390A) and I bought enough 
silver mica caps from Mouser to do an IF strip rebuild.

The reason I chose those particular types is what I perceived as their 
reputation for quality and reliability and as one list member said...I 
only want to rebuild/remanufacture my radio once! It's not going to be a 
museum piece, it's going to be a radio that I want to use on the daily 
basis for the rest of my life.

Having said that though...do you guys think I have gone overboard with 
my choices (716 series Orange Drops and Silvered Mica) as I've read that 
Ceramics seem to be good enough to use almost everywhere. The reason 
that I didn't choose Ceramics is that I read somewhere that the Silvered 
Mica were a step up from the Ceramics.

I have a further three R-390 series radios that are going to get the 
full rebuild treatment so if there is a better choice out there I'd like 
to know. The radio I'm am doing at the moment is my first R-390A rebuild 
and I am planning on doing one a year...then I can sit back and relax 
and enjoy the fruits of my labors!

Regards,
Ken
