Hi Chris,

Without the LPF, it is even less critical because there is a pure resistive load for the whole output spectrum.
So just do it...

Hello LF'ers,


Push pull output, Class D low frequency (136kHz) RF amp, circa 500
Watts. If I want to test it for a few hours into a dummy load does it
matter if the low pass filter network usually used is not between the
output transformer and the dummy load? I want to leave it running
overnight and I am modding the LPF and it's in bits until next week.
Thanks.
