HP9100B: transistor specs needed

[isanchez]

Hi,
This week-end I have been trying to repair my HP9100B, or at least to identify the problems...With the great and valuable help of James (see his post about the repairing process of his 9100A) I believe I have made great advances.

Now the display works (only a spot was shown before). It shows very well focused three lines, but with nonsense content...(see picture). It reacts to any keyboard entry, even the programme/run switch...but with nothing readible.

Checking the transistors I found two of them that, when touched, made the display flick, and even turned it off permanently. I suppose this can be one of the reasons of the failure (I wish the only one!). I enclose a picture with the location of the transistors. They are in the most left side board, the one screwed, not the easily removable.

May I kindly ask your help to identify the characteristics of these two transistors? Where can I get spares?

I appreciate very much your help...like always.

Best regards

Ignacio
