[Premium-Rx] RA-6790GM front end FETs ....part numbers?

[DANIEL HIGGINS]

Paul,

If you are going to remove BSV81s from an old module remember that they are 
static sensitive (protection diodes are not good for IMPs).  Wrap some fine 
wire around the leads several times before you try and remove them.  I 
remember when I was at Racal building a mixer board with BSV81s and I forgot 
to remove the conductive rubber band that is used to short out the pins. 
The smell of burning rubber is a bit disconcerting when you first power up a 
new board!

Good luck,

Danny
