See the schematic for the Centurion. Although I recall the board being
different, the filter circuit is the same.

I did the mod from the schematic and parts that T-T sent on a perfboard -
it really isn't much, but, before hand, I pulled the 15 meter filter and
put in a jumper wire - it worked like a charm w/o the filter - I am not
sure what the harmonics on that looked like - others can do the hi-tech
work :>)

I just acquired a Ten Tec Centaur 411 amp from an SK estate. As it turns
out, it was never updated for 12/10m use. Ten Tec noted they did not
have
the board to enable 10m. Any suggestions on a possible source or circuit
diagram would be appreciated.
Doug:
Had to do this to our club Centaur. TT no longer has the plug in board
but
will supply the pi-section filter schematic/parts values for it. You
have to
fabricate your own board, which goes in place of the 15 meter output
filter.
Have fun..
