Life of KT 150 Tubes

Auris audio Mono Block -Forte 150 uses Two KT150 for power output for each monos, Very strangely a both amps popped the KT 150 same time. I can vouch it had less than 1000 hours in 2 years as I have NAIM NAC 252/NAP 300 in the same room. I tested the tubes and one is 100% dead and the rest have very marginal life. With great difficulty I have ordered four new tubes. Would any of you know why this would have happened, in the sense bath amps not working at the same time? I am trying to get hold of Auris in Serbia. Even a good Valve tech will not open the unit without schematics and Auris wouldn’t provide one. I am in Canada. There are 2 authorized service center in the US. When crated both amp weighs 94 Kgs.Not easy to ship. I tried with a borrowed set of TUBES , there is no Biasing at all,mA reads 0, but there is signal coming in and VU display lights up. 

Lesson learnt well not to buy equipment that is hard to service. I bought this even before there was a dealer in canada. I tried contacting the distributor Motet in Toronto. They are telling me to contact Dealer in Edmonton 300Km away. He never sold me the unit, why would he have any interest if he didn’t make any money on this unit? The unit cost $16,800 USD. Any advise what I should do?

Really heart breaking story. That is a huge investment… in what should be a trouble free set of amps. Sorry to hear it.

Road trip?

I worked for a Japanese company for a long time. Our office was in Vancouver Washington. Sometimes some of the Japanese would fly into New York and think they were going to take a few days off and drive from New York and see America on the way to Vancouver.. This lasted as far as Pittsburgh usually… one group made it as far as Chicago.

I lived in Edinburg Scotland for a year. When first there I asked a colleague where he lived and he said on the other side of the country in Glasgow. I was aghast, I asked, “do you have an apartment here?” No, I drive… it is 45 minutes.

I lived in Tokyo for a year. Most of my colleagues commuted 2.5 hours to work and 2.5 hours back. I ended up managing two teams there… both in Tokyo… it was a 2 1/2 hour commute each way every day… by train… frequently smashed at 2AM after a business diner.

It is all relative.
