Transistor Replacement

[teenix]

Hi all,

I'm looking at a HP-97 for someone with a dim display and it needs one or two transistors replaced. One is a current bypass for the charger which has the casing face detached, probably from overload and the other one supplies current to the anode drivers.

1853-0393 and 1853-0374 both PNP's.

Funnily enough, these parts, and parts I've searched for in the past using the HP X-Ref file, yielded no matches.

I've seen previous posts discussing parts matches but I cant locate them.

Any ideas - probably general purpose PNP's will do - 2N2907 etc.

cheers

Tony
