Can one turn on a solid state amp without a load?

I have a Jeff Rowland solid state amp, a model 5 stereo
Amp.which makes a loud thump when I first turn it on.if
It gets shut down and back on before a week it turns on fine. Once it's warmed up it fine.

Thanks for getting back.i have some things to take care of and have not check for a response. I guess it won't hurt to replace them. How many are there?
