Recently I'm purchasing some power supplies. What surprises me is that fo=
r some very similar power supplies, MFJ-4225MV

http://www.mfjenterprises.com/Product.php?productid=3DMFJ-4225MV

and VS35M

The latter one has an adjustable current limiting function while the prev=
ious one has not. The rest are quite similar. The latter one is a 29 lb a=
nd the previous one is only 3.7 lb! The dimension is also doubled.

What makes this big difference, the MFJ one does not have a transformer i=
nside?
