Hi ION,

Have you completed your tracking supply amp.

Meanwhile while I am also developing a tracking supply amp with tracking only on one rail as the amp is self centring grounded bridge type using all N-channel Mosfets....

hello guys,

please I would like to know some comments here or some unbias ideas from the experts of amplifiers here. im no expert on amplifiers but a general idea from you guys would help a lot.

which would be much better between these two designs....it will be mainly used for driving bass speakers

first...a 4 steps class H, almost the same as Ion use... the voltages from the transformer are as follows.. 35V -73V-111V -141V
it puts out 1800 watts @ 8ohms

second ...same as lab gruppen design, TD
