Hi Semi, thanks for the acknowledgment & glad you are happy with those mods.
Improving your BAT 150SE
Most of you are aware of David's (davidgarretson) mod which includes coupling caps, input wires, and rectifiers. I just had mine modded, only the first two items. what I wanted to share with you is the input wires.
150SE is bridged internally from a 75SE, both input and output. both input are wired from XLR jacks to the main PCB, but you only use one input as the signal is shared using a cheap jumper near the very front of the amp. when you replace the input wires, skip the jumpers and run your input wires from XLR jacks to one of the main PCB and continue to the next PCB. I kept the ground wires in both, but removed the input wires of unused side to reduce RF pickup.
with caps and wire change, you will hear improve definition, speed, ambient retrieval, and probably details. well worth the effort and money.
thanks to davidgarretson for sharing his experience with happy BAT owners.
