  Hello All,
   

          I had an older FT-857D (2002) come across the bench last week with
a blown VHF/UHF PA final 2SC3102. HF PA was OK. That used 2 x  2SC5125's.

         My FT-857D (made in 2007) uses RD60HUF1  in the VHF/UHF PA final
and 2 x RD70HVF1's in the HF PA.  Yashue re-worked the PA board to allow
the use of the diff. zitters.

         I have been unable to locate a manual that reflects these changes.
Was wondering if anyone has a link to it ?

BTW:  An early FT-857D with a blown VHF/UHF PA final 2SC3102 will pull
         9.7 AMPS when in RX.

TIA

/Dan
