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 :>)

Ooops... there goes the FCC type approval.. ;-) (hope your antenna was selective)

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..
