Tube Failure question
I am new to tubes. I have Primaluna Prologue mono blocks. I have had the amps for about a year. Also using solid state bryston preamp. Lately I have popping and at higher volume last night some screeching sounds that go away at lower volume. Can this be a tube failure? If so I would like to have good sounding tubes with as much power as possible. Suggestions? I am assuming that the power tubes are the large ones. Is this correct? If so suggestions for the smaller tubes to sound warm and musical? Speakers are large with separate horns and tweeters. I live in Canada so if possible would like to buy tubes here. All suggestions welcome. Thanks, Tom

Thanks to all for the advice as I said I am new to tubes so dont really know the pros and cons of different tubes. I have not contacted Primaluna but will now thanks to the advice here. The small tubes I have are 12AU7 and the large ones are KT 88. I see suggestions for EL 34 and Tung Sol 7581 Can someone give me there thoughts on the differences between them and KT 88? Lastly the noise does sound as if the amp is clipping (popping) but is not consistant. Am I right to assume tubes? Can I but tubes somewhere in Canada? I am in Ontario. Thanks again. Tom |
