我已帮你发帖问AL先生了
他很快就作出回应。。。。。。你真幸运。。。老外专家们的热心程度真令人感概。想想国内。。。唉
下面是他的回帖。他说早期即1993年至1994年的4240使用的功率管是BUK553-100A(我小鬼头大致记是西门子或其它欧洲的MOSFET型号,后面的也是),后期的BUK555-100A或BUK555-100B。
另外,他要求给出板子的版本号码(版本修订号码),他可以提供4240的有关资料(可能包括线路图。。。我要通过E-MAIL跟他联系)。

Early 4240 (1993-94) used BUK553-100A, later BUK555-100A/B was used.
Drop me a mail and I'll send you 4240 diagram - it was published by me in 1998 in "RadioHobby" magazine. Better if you'll check and mail me the board revision number, as there were several revisions to 4240.
Cheers
Alex
