Life of KT 150 Tubes

I am a novice and know nothing about this (hasn’t stopped me before), but I have an idea.  As several members commenting here seem to know a lot about testing electronics, including tubes, perhaps one or more of them could offer to check out OP’s unit and see what they find?  I don’t know OP’s skills, but if it were me I would be in the dark and welcome ANY knowledgeable help.  Maybe arrange a time for OP to drive down with units and get a chance to hear the helper’s system while the units get checked?  Maybe some local sights to see.  Preferably not involving a real long drive?  (I’m a Buckeye but admit that there are some very smart, knowledgeable Michiganders (or Washingtonians, New Yorkers) that might help in a situation like this).  Just an idea.  Good luck to OP. 

I hope all goes well on your road trip to the dealer.  The good thing about tube gear is that pretty much everything is repairable, and because the circuit is relatively simple, the cost should not be very high.  The exception would be something that damages the output transformers (very unlikely) or the power transformer (more likely, but still not that likely--the fuse should prevent that outcome).  I don't know if the dealer can do a while you are there kind of repair; let's hope that is the case and you don't have to have the amps shipped or you don't need a return road trip.

@ jerryg123.  You've been lucky.  Isn't that nice.  Why comment on something you know nothing about, much less hurl a pointless ad hominem attack? 

You obviously have never had to ship a 100 pound amp back to the manufacturer for repair.  It costs about $200 to either coast, each way, from where I live.  It costs considerably more if you do not have the original box or do not wish to lift and pack it yourself; recently it was c. $360 by Freighters and Craters, one way.  I do not intend to ever ship an amp to Europe or China, but I do plan to keep supporting US manufacturers.   

@vishu ...asked me to take it to Edmonton 300 Kms away to their dealer. I am going this morning and will keep you all  posted.

How was the trip to the dealer in Edmonton back on 4/17 - were they of any help, any luck? Curios to learn more about what compromised your KT150s. Thx. 

@decooney - It’s been 2 weeks since I dropped of the Amps at the Dealer. So far no word yet . Dealer did mention amps will be sent to his Tech and it will take 4 weeks  at the least. Dealer did say he received the schematics from Auris and the case is ‘ out of warranty service’ as I missed by 4 months. Mean time i have already ordered KT 150 from Germany , cost me less than 1/2 the price of canada and USA .KT 150 is made only by Tung Sol and they are Russian . I called supplier in the US , shocked to the hear even though it is in stock they are banned from selling because of sanctions.  KT’s are hard to find.Now I am afraid Custom duty will be very high because of sanctions. Will  find out when I get it.
