More power on 28MHz

I've been using JT65 on 28MHz quite a bit recently, with 5 watts from my FT-817. I thought I'd try using a bit more power, remembering I had a Euro CB EA-150 amplifier that I'd not used for a long time.
With 0.5 watts input (the lowest power setting on the 817), it was already putting out around 35 watts at 28MHz, which was quite enough for a weak signal mode and transmitting continuously. I think it will do about 100 watts, which means that at a normal CB type drive level (4 -12 watts) it wouldn't be a very clean SSB signal.
The transmitted signal is OK, I'm getting received by some stations on 28.076.
