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.

Yes, when all is okay. Yours sound like the PSU caps are leaky and need replacement.
