Angry Help with dared MP-15, please!

Click the image to open in full size. Click the image to open in full size.

Hi, this is an integrated amp from Dared that was working perfect until a couple of days ago when the left channel suddenly died, there is no hum, no distortion, nothing, I canīt see anything burned or loose, all I can tell you is that the KT88 in the faulty channel barely gets warm, the other KT88 gets very very hot, or course I tried changing tubes, but it seems that the KT88 is not getting enough current to heat the filament or something similar, what is a safe way to measure this? thanks guys! ah the other tubes are 12AU7, 12AX7 and the one in the middle is a 6HU6.

Get a multimeter, set it for AC and see what it reads between pins 2&7. Who put Auricaps and the red electrolytes (Cerafines? BGs?) in there?

the auricaps and cerafines are stock, not bad for a Chinese amp, right, I will take the measure tomorrow, thanks, what would be a normal reading?
