Hi All,
For some strange reason I get a lot of help requests on Aleph amps, most of which I can answer easily ....... however, this one's got me stumped !!
Could one of the EE theory types offer any help?

Dear Mark,
I'm building your Aleph4 version and experiencing some problem. All seem to be right but when turn on without load (I try first on speaker and burn it), voltage at output goes about 84V (power supply is +- 42V) and burnsR22 and on FET boards the Mosfets and resistors asociated (.68 e 220 ohms), that relate to the s terminal (not S).
Thanks for advice

PS: I have already told him to check that the pin configuration of his FETs matches and that they are installed correctly, can't see how this would occur unless FETs are installed incorrectly ;-)
