I have the 400 with PSB Imagine T2 Towers and before getting the PL, I had to use a Sub and now, man, I almost have too much bass lol. If you find the warmer preamp fix that is great. Also, if you go to the KT series of tubes, you will find maybe what you want. Take care

Hi Kt88 and Happy New Year! Sorry for the late reply. Makes total sense about the phono "noise" and as for the rest of the issues, I lifted and reset some of the front tubes and now it is fine as for the "noise" I was hearing. Fido mentioned that simply lifting and resetting can cause the tubes to properly connect and that is what I did and I have to say that I just love this amp. I really appreciate your reply and concern and I have to say I love your country. When I was 18 I hitchhiked from Helmstedt to Berlin. Saw the Wall when it was there and every German I met was just the coolest. My favourite band in the 80s was also the Scorpions! Of course, that was when Michael Schenker and Uli Jon Roth were part of them. Anyways...again...thanks.

You will simply love the sound that the 400 produces. Good luck with your purchase. Cheers

Thanks for your reply Erik! I am new to this all and am slowly gathering information from this forum and others. The people on this site have been so helpful and friendly to me and I just wish I could give back somehow but I am a noob. The amp is simply beautiful. I can't state that enough. I am covering it now when not in use to avoid any sort of dust accumulation and will try to clean as required. Anyway, Merry Christmas to you and all others on this thread and elsewhere who have helped me. And of course, have a Happy and Healthy New Year. Cheers

Hi Erik, Thanks for your replies. I did remove the tubes and re-insert and the noise is now gone. I am not sure what was going on with it but I think it is fine now. All the best and I really appreciate your care and concern. Cheers

Thanks Randy, I unfortunately don't have any other tubes. I did look at the pins and they seem to be straight and normal looking. Will try to get help thru the dealer. All the best. Take Care

Thanks for your help. But, the sockets are not in fact loose. I thought they were at first because the tubes in the sockets were moving so freely that I thought the sockets were the cause. The tubes are the item that are loose. Thanks Take Care

I will do that right now. I really don't want to harm PL's reputation at all. Despite the bumps I am having, I am floored by the amp. Just in awe of the sound it produces. Thanks

Loose Sockets Correction/Loose Tubes in Sockets on PL EVO 400 Integrated Hey Guys, Thanks again for all the help guys with my noise thread. I want to re-state something I said earlier which was entirely wrong. Being new to tubes, I stated that 3 of the front tube sockets were loose. They are not loose, but rather the tubes are loose fitting in the sockets. I thought it was the socket moving but it is the tubes easily moving when I wiggle the tops of them. I do feel the appropriate amount of shame. But is it normal to have loose tubes? The rest are pretty solid up front and the power tubes are in there like cement. BTW, the front tubes are in the sockets all the way. Here is a 12 second video of the loose tubes: Dropbox - Valve Movement.MOV - Simplify your life Cheers and again, I am sorry I stated the wrong thing.

So, finally had time today to do a re-arranging of tubes. What I did was move the two preamp tubes in the middle (Number 11 and 12 or 3/4 to make it easier) to the right channel sockets 13/14 (5/6). The rattling, crackling sound went away and it isn't dead quiet like before but there is a real negligible hum. Please help me with this if you could....guys....we have two pre-amp (gain) tubes in the centre slots and two driver tubes on each side of those pre-amp tubes. What would cause noise in the first place? Could a faulty driver tube cause it? Only a faulty pre-amp tube? (not looking at the power tubes) Or, could any/all of them cause it? If it is the two centre tubes only then I guess I should put them back switching the positions they were in. Left to right and right to left as the noise was mostly from the left channel. To add to it, when I was about to do the swap, I gently grabbed the tops of all the tubes(driver included) and made sure they were set in place and discovered that the 9 and 10 sockets were definitely loose and the 13 was slightly loose. The rest were totally solid. Confused in Canada lol. Again, thanks for all the help here guys. Any suggestions welcome. I just want to fix this and move on and listen to my records and stream music. Cheers

Thanks Fido

Hey Guys, So, on the weekend my amp started to make a sound when the volume button was turned down to zero and it was present on all the different AUX inputs. What does this sound like to you? The amp/tubes? Electrical Line issues? At the 28 second mark, I turn off the amp and you hear the lovely crackling sounds of the tubes lol. Thanks so much, Cheers https://www.dropbox.com/s/0dwdb6veo5mmafr/New Recording 12.mp3?dl=0

Hey Guys, So, I was documenting that I had a phono-stage issue with a "snowy" sound when I turned the volume up to noon on the dial and nothing playing. (this was a very minute sound but audible) So, I imagine it is the phono-stage causing it or the cable etc. But, now, after a month of having the EVO 400i, the channel that was clean and free of "noise" had tube noise with the volume knob not even turned up. It seems to have subsided today but it is not entirely clear. Does this happen the odd time because of our electrical connections? Have you had this just arise like me .... no noise on my channel for my streamer and now it is there? Thanks

Heard good things about the Willsenton R8 as well. Many YouTube reviews on it. And the price...amazing price. Good Luck
