Re: MN2000 bandswitch parts and capacitor info needed


 

Ed,
?
Thanks for sending the link to that Drake group discussion on the MN2000, it is very good, Jim's discussion of the capacitor bank configurationis especially helpful.?
I followed one of the links on tuner theory from that discussion and it illustrated the potential hi voltage and RF currents that may be encountered within the tuner at various impedance mismatches.? Although they were for a different tuner configuration, the voltage varied to as high as 2KV with a 2KW input.?
Since the MN2000 is rated for Full Power up to 2KW, I'm making the conservative assumption that similar conditions could be present in the MN2000 and need to spec the capacitors accordingly.
However, most of the mica caps of this case style (and proper capacitance value) that I have found thus far have had voltage ratings like 600V, but still looking.
?
Still hoping someone snapped a pic of those capacitors or maybe has a Drake part number cross ref to a mfg number.
?
Thanks
