Help with a new Tube headphone amp blowing fuses

Received a new headphone amp this week to replace one from same manufacturer that is still serving me well but wanted to try a little more power, new amp 1.4 watts versus a .35 watt on the older one. Have about 25 hours on new amp and turned it on this morn loaded CD and after about a minute the music was replaced with an elevated fuzzy noise right before fuse blew, replaced fuse and it blew a second or two after turning unit on, saw nothing unusual going on with the tube glow, replaced New amp with the older amp in system and all is well. What are the possibilities of fault here, would like to handle myself without having to send back to Japan for warranty work.

@raindance , I am happy to say that the answer is yes, Yamamoto responded with their FedEx account info, unit was shipped back to them, transformer replaced and the HA-03 has been working great since and it is marvellous. Yamamoto was very apologetic the turn around time was less than a month and I incurred no cost.

@raindance , I am so glad you reached out for a conclusion on my Yamamoto headphone amp, I was pondering reaching out to you on a pair of VTL MB125 mono amps that I have had for 20 years and are in need of repair. Amps had been in play all those years when I pulled them out of play 8 months ago to verify the working of another pair of Amps I had sold and was getting ready to ship to the buyer. When reinstalling the VTLs one of them blew a fuse and started showing signs of distress, exactlly  what I do not remember. I purchased a new pair of Quicksilver M120s and boxed up the VTLs and they are now in storage. Would you be interested in going thru them and bringing them back to life? Time is not an issue.
