7L14 - no 1st LO output


 

¿ªÔÆÌåÓý

Hi Guys
Information please. I have a 7L14, where the 1st LO has just died.
It seems the main YIG driver transistor, an NPN Darlington, has already been replaced
The Tek part number is 151-0454-00, but this bears a Motorola number SJ6796 and a date code of 8018.
?
Despite searching all the usual places (net/databooks)?I cannot find any reference to the Motorola part.
Anyone got any information about it they are willing to share?
thanks
Chris HJ
