List, IIRC I've seen 3 published articles for r390a to r725 conversion all using the re-wiring of the R390 IF to 6 volt filaments. This seems to be a big PITA. When the military did the original they just added another 26 volt filament xformer. This seems a much easier approach especially when we have small SRPS's available.
If anyone would have the schematics or TM addendum I would appreciate it if they would contact me off list. TIA Perry ______________________________________________________________ R-390 mailing list Home: http://mailman.qth.net/mailman/listinfo/r-390 Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
