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.

Hey shubert,

C'mon down to Texas and learn some manners. Even you might be redeemable, but no guarantees.

Just don’t burn any American flags while you are here.

tooblue - I am a Camel fan, so the moniker is related to their album Raindances...

Raindances is one of their better albums.

@tooblue , what happens if you replace the power tubes? Does it still blow the fuse?

Do not have extra tubes, it uses an obscure C3M Siemens. When the fuse blew initially I was listening and the music was replaced by an elevated hissing distortion for about a second before fuse blew and didn't see any tube glow anomalies.

Never heard of the band Camel but just googled them, don't know how they got by me being a product of the mid 60s.
