вот что пишут про модель tfx700:
Reliability: 1
IMPORTANT: this amp is a solid state tube hybrid,, which means it is still primarliy solid state,, however i have had more problems with this amp than my dads 67 blackface dual reverb!!!,, at first the effects would sometimes everyonce in a while come on even when i had them turned off,, but when i took it back it wouldnt do it for the repair man,, so it ultimately broke at a show!!,, then i took it back and they sent it to laney finding that the effects board went ,, and when it broke i took the amp apart myself only to find that screws from the board were missing and parts were poorly assembled ,,, PLEASE if you own a laney take it apart and look for yourself because they have the worst assembly line,, they put NO effort into puttting this thing together with care!!!
so anyway, when i got a BRAND NEW replacement amp finnally after waiting for the terrible people at laney to get it here. i was happy to have a new amp and stayed that way for ONE month,, it has now been two months since i got the brand new replacement head and the SAME exact thing is happening!!!! i am so mad and i will never buy a laney again,, my advice to anyone that owns this amp is to through it out the window,, go to you nearest Mesa Boogie dealer and buy a Dual Rectifer!

вроде очень не надежная вещь, да к тому же написано, что он ПОЛУТРАНЗИСТОРНЫЙ. т.е. solid state tube hybrid.
