Is there much difference between 6BQ5's and 6BQ6's??

I see EL84's listed both ways on web sites with some calling the last number 5 and some 6, but I know there are both tubes out there.

Thanks

I would have thought that the 7 pin base and the anode cap of the 6BQ6 would be sufficient of a giveaway;
No they are not the same, you are looking at a misprint.
6BQ5 = EL84
6BQ6 is a bit like EL36 if you squint - it is really a 50s TV valve.
