[TenTec] Jupiter 538

[ROLAND HOWELL]

Hi Folks

A bit puzzled by the component / circuit diagrams in the user hand book 
of the Jupiter, the PCB 81889 Rev A board shows Q20 as being a 2SC1971 
whereas the 3 legged fuse fitted on my board is a RD06HHF1!.

The PA board 81897 also shows finals as being SD1405, mine are MRF454 
even the drivers that are supposed to be 2sc3133 are different.

So my question(s) is/are, did changes take place during the assembly run 
for this model to either or both of these boards.

As always advice greatly appreciated

Snowy
