I have contacted Linear Systems in the US as they have a LS3250A/B/C dual transistor. But they did not recognize the 3250 marking on the top on my device.
So they asked what it says on the underside of the dual transistor. It says "9705".
There are two of those dual transistor in a Cranesong Spider mixer made in 2002 in the preamp section. I am unable to reach Cranesong. No answer on e-mails and no one answer the telephone... The mixer have a terrible "popcorn" noise on three channels. And i suspect the 3250 transistors.3250 Dual MatchedTransistor .jpg3250 Dual MatchedTransistor Top.jpg3250 Dual MatchedTransistor Underside.jpg
