From what I know, the AFD100 is a modified plexi (1959T - the tremolo was removed and portion of the circuit was used to hotrod the amp), the #34 is a modified JCM800, used by Slash on the UYI and beyond....the Silver Jubilee might be based off the JCM800 I don't know..(the amp in the 92 Tokyo tour is most possibly the Jubilee)..but circuit wise and sonically the Jubilee I read is different from the channels on the AFD100.
I had looked around to obtain this information when I got my AFD100....
Check this video out, it is the Jubilee
