I absolutely love my VK-P10SE Superpak (which I purchased from Jfrech!). I sent it to BAT last May for the AC balance and new-style superpak upgrade. It is serial number 027, and has been incrementally upgraded over the past several years first by John and now by me. Unfortunately, due to the age of the circuit board, they did not feel comfortable changing the transformers to the Lundahl units (which is a non-issue for me, as I do not use the transformer). Whatever you do, get the serial number of the unit you are considering and check with Victor or Vladimir at BAT to determine the history of the unit and the potential for future upgrades (such as the AC autobalance circuit). I highly recommend the VK-P10SE superpak!!
