Is what you are saying that MOSFETs takes more beating without going up in smoke? If that's the case, this would explain why they are used a lot in PA audio systems.

MOSFET power devices are often used in the output stages of amplifiers (audio, motor control, heating control etc) that maybe subject to abuse as the devices characteristics when overload occurs are inherently self limiting to a point (unlike conventional bi-polar transistors which can suffer a self destructive failure called thermal runaway). -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
