I have recently aquired a TL-922.  It is on a stiff 240V line which actually
measures 245V.  No load voltage on CW is 2200 and on SSB is 3100.  Under
full load the CW drops to 1900V @ 600ma and the SSB drops to 2400V @ 800ma.
Is there really suppose to be this much drop?  It has the original 200uf
caps in it and I was thinking about replacing them with 560uf units.  Also
the grid bias on CW is 60ma and on SSB 120ma which seems a little low.


thanks
