I have finished a jlh69 amp,published in the EW (may 2000)
I can say, in comparising with mine rotel amp,
the jlh is the better one.
A great amp for such a simple design.
For the power supply, i will use a capicitance multiplier
(shown on the class-A Amplifier site)
I wondered is there any sound difference between this and
common C-R-C power supply.
