Well I finally got around in building my 2nd bass amp. I do have some noise issues with the preamp. See the link.

One interesting thing. When I plug in an 8 ohm speaker into the 8 ohm jack, the preamp circuit works but noisey. When I connect 2 - 8 ohms cabinets into the 4 ohm jacks the preamp cuts out. I can still use my DI and by-pass the preamp. Strange.
