Replacement for KSA-50

Hi Amp Gurus,
I have a KSA-50 that is 10 years old that has blown one channel. I use it to drive Thiel 3.5. Is it worthwhile repairing the channel or buying an used amp for less than $1000. Please let me know if there are any good options that provide the same quality as KSA-50.

Thanks,

The Krell KSA-50 is a great amp also runs hot. It is a good ides to replace the four original 40000uF/75V filter capacitos with 47000uF/100V caps. I recommend either Nichicon 47000uF/100V or Epcos 47000uF/100V caps. Nichicon is made in Japan. Epcos is made in China. Also Cornell Dubilier 47000uF/75V caps made in USA will also work. Total cost $375.

Thanks for this tip! I will keep this in mind . Will this replacement do any SQ improvements or does it just make the amp less hot?

Thanks,

Yes you will hear a huge improvement in sound. Also using a higher voltage capacitor the cap will run cooler.
