Looking for advice - Mola Mola Kaluga amp has no output

@deone, you must be right, but i am refraining from making any judgment before Hypex gets back to me. They were all busy with Munich High End so this is going to take some time. This is going to very useful information for all of us, as this goes to the heart of power conditioning/protection/supply topic. I will be sure to keep you all posted. I am working with good partners at GTT/Mola Mola. Thanks

@hgeifman thanks for taking to time to respond. I have followed all of the above and its still non-functional. At this point it is evident to me that this needs repair. Let me wait to hear from Mola Mola. The fact that the units are powering up but are cold to the touch, and fuse isnt doing anything, means there is little i can do at this stage....thanks again.

@hgeifman many thanks for your immense help here. I will connect with Bill (he is actually in NJ, not too far from me) and keep you all posted, as this mysterious problem might of interest to many. Thanks again

@deone thanks for your response.

1. Yes, tried

2. XLR input from Zesto Leto preamp. I do not think Zesto is the issue, as the headphone output is working fine. Also both output tubes going out at the same time is rather unlikely

3. It is class D, but it gets warm when on. I have had these for years, they are never cold to the touch.

The one last thing i will do is change the xlr cables from Zesto to Mola Mola, but again two xlr cables going out at the same time just isn't likely.....what a mess.,

Thanks all but i will wait to hear from Mola Mola and GTT before anything else, it is a great company and a great distributor with support reputation to back them up. Will keep you all posted.

All, apologies it took me a while as we were in Europe on vacation. Current situation:

1. GTT very helpful, i had to ship the amps directly to Hypex and paid in advance for power supplies, with no guarantee that this indeed is a power supply problem. If it is something else i am assured my payment will be adjusted towards whatever the problem is.

2. It is stuck in customs now for 2 weeks. Once it gets to. Hypex i hope to get some updates.

3. I contacted PS Audio about Stellar. Their first answer is that Stellar is more of a regenerator than a protector - quite different from what the product description depicts on their own website. Either way, they have no insurance available for connected equipment, unlike many much less expensive alternatives who offer this cover. 

My learning from this: NEVER plug in amps to anything except the wall. Everything i had connected directly are totally fine. 

I will share more as i learn more. Needless to say, HUGE thanks to so many of you who helped me through the process....Much appreciated.

Must add: I just bought a Primare SPA25 as a temporary solution while the Mola Molas are out. This multichannel receiver will eventually go to my HT system and replace a Yama Aventage receiver there, which i was planning for anyway.

The SPA25 is quite unique for a receiver - very good build quality, quality dacs and amp modules, roon ready coming soon and has dirac live for use in HT system later. It's still burning in, but must say sounds reasonably good. If curious, check it out online. Must say, for such a high build quality its reasonably priced, but getting it to work was a total nightmare - very poor manual and you cannot set up without a TV (i hate that)...once set up, everything is good. Roon ready supposed to come in June according to distributor i spoke to.
