[R-390] Replacement IF filter?

[John Flood]

Greetings,

To offset the total shock that my R-725 (and other BA toys) had when they saw me 
working on a Harris RF-350, a 1958 Motorola R-390A fixer-upper... well almost a 
parts unit but hopefully a fixer upper and two parts IF decks followed me home 
last night.  I was looking at the IF deck in the radio and there are three 
collins filters and the 4KC filter has been replaced by a filter by 
Whitewater Electronics.  I scanned through the pearls and saw one reference to 
this company.  Just curious how common these are and if there is any thought 
about quality or longevity of these filters.

Now all I need is a BFO PTO, PTO, meters, function switch assembly, couple of 
knobs, fuse holders, shaft couplers oh ya and money from sales at this weekend's 
flea to pay for them all.  Add in some good luck with the parts that are still 
there and I'll bring another one back from the dead.
