I'm trying out EF91 tubes and 6J1P-EV tubes, where do I put the jumpers on my Little Dot mk3?  Right now I have both of them in.

Well M, they are both from different families.  The 6J1P-EV  are from the EF95 family.  I don't have the MKIII but the MKIV and jumpers need to be changed for those two families.  They are not the same.

Right now I've got EF92's in there.  Would I probably need to use the same arrangement that I have for them with the EF91's?

EF91 and EF92 families use the same jumper setting. EF95 types are different. Here's the manual in pdf format.

Perfect thanks!!
