Adjusting the bias and replacing the tubes in Cayin MT-45MK3 aka Jazz 80 tube ampliifer

So this is the third video on this superb amplifier. This time I wanted to show you how to replace all tubes and how to properly set bias for power tubes after replacement.
Specific questions? Ask me in the comments as usual :)

Using a PrimaLuna DiaLogue Premium HP Integrated and have installed KT-170's). As for the grease on the Audio Tubes, clean your hands, wear gloves but, grease ONLY effects (short bulb life) Halogen Lightbulbs.

Siema! Spoko filmik. Ale jesteś pewien, że MT-45MK3 ma 60s soft startu? Wydaje mi się, że nie ma.

Yes it has, but it's more like 30sec maybe. To my surprise even the official product page for the tubes version I have specifies that it has slow start circuit. Surprise, because the first versions (these with very exotic tubes) did not have that feature.

Zakupiony w czerwcu 2024 w oficjalnym sklepie nie posada miękkiego startu. Lampy ECF82/6U8, 12AU7/ECC82, KT88.

Look at the picture right below case disassembled chassis photos for "Soft start design: 60s mute delay". I can't post screenshot here...

@@k4syx Wiem. Dlatego napisałem w recenzji, że wprowadzają klientów w błąd i wkleiłem to zdjęcie.
Jeśli byłoby jak piszą, nie powinieneś nic słyszeć przez 60s od włączenia, a tak nie jest

@@vanderstar317 so that one review with photo I saw there was from you, right?
As I've said in my amp there is about 30s (maybe 40? But not 60) when it's dead quiet with source signal on, and then the sound starts to "emerge" from this silence. I've literally asked them via messages about that when I was prepping the video, I may reach Cayin again stating that one of my viewers has some doubts on it if you'd like me to?
