Esoteric Audio Research V20 tube layout


Hi Folks - I have had an EAR V20 for many years now and have enjoyed it very much. It came time to re-tube and I've made a pretty dreadful mistake. I cannot recall which tubes go into which slots. I know that there are ten 12AX7's for each output stage and they occupy the front 10 spaces on each side but I am not sure where the remaining tubes go which are a mix of 12AU7's and some more 12AX7's.

I don't have any owner's manual so I cannot access the information if it were on those pages.

I do have an inquiry out to Dan Meinwald but I thought I'd also ask here, as well.

Thanks in advance for anyone's help! :-)

Thank you for your answers. There are a grand total of 30 tubes on this amp! 15 on each side. 
I believe 13 of the tubes are 12AX7's and 2 of them are 12AU7's, if my memory is correct. 

Hi - I just heard back from Dan and he informed me where the tubes are meant to go so I'm set!
