Looking for advice - Mola Mola Kaluga amp has no output


Hello all and happy Easter. Hoping to get some tips from experienced Agoners. My Mola Mola Kaluga is giving some trouble - no sound. It is powering up but is cold to the touch even after hours. We were out on a weekend vacation and when I returned it was on standby mode (maybe power failure). It is plugged into my PS Audio Stellar Powerplant 3. I am completely puzzled because it is powering up fine, i changed the fuse as well, to no avail. Any clues from Mola Mola owners out there? I have written to Mola Mola and awaiting response as well. Thanks in advance for any help!

Two questions:

1. Have you tried plugging in the Kaluga directly into an outlet rather than the power plant?

2. What is the input into the Kaluga? Have you been able to verify that this is working?

3. Isn't the Kaluga class D?  If so it is not surprising that it is not getting warm especially when not playing music.

Question: Aren't the Kaluga monoblocks?  if so, isn't it strange that neither of them is producing any output?  Can you borrow any power amp and test the preamp out?

Good luck @musicmatters1206 .  I am still puzzled how two monoblocks died at the same time with the same symptoms...it cannot be a fluke and it must mean that something feeding into the monoblocks must be responsible; could be the powerplant or the preamp.  Would be worth making sure that both are checked and tested carefully so you don't damage the repaired amp.
