Could you recommend an amp for my unpowered Kemper - into THD 2x12 cab?

Hi.

Not really in a position to buy a Friedman or Atomic-like powered FRFR cab at the moment so was hoping to run my unpowered Kemper into my existing THD 2x12 guitar cab. I wonder if you could recommend an amp, preferably rack-mount, that'd be good for the job?

Nothing with tubes though... I've bought my last tube.

Thanks in advance.

Thank you. Much appreciated.
