 I understand the AA91 to be a later version of the W7. I understand the AA81 to be a later version of the AA10. All are EL34 monoblocks, with 6an8 driver tubes.

But what are the differences between the 2 series ?

Thanks,

Ross

 The AA-81 ia tube rectified and the AA-91 is solid state rectified..Other than that there isn't much difference as far as OPT and tube complement.

Thanks,
