I've done some research on dual rectifiers but I'm still a little confused about which are good or bad. Is this one of the good ones and is it worth the price? If not what should I be looking for? Thanks!!

Found this one today and want to clarify that it is a real IIC and it do have a ++ mod. The seller say that it has an additional volume knob which have been wired to the reverb knob and the tank is removed. anything that you can point out?
