Thanks, this was the testing phase so it was still messy.

I have not done much listening without the tube pre. Its purely phono for now. It is the ebay VTL 12ax7 phono pre board and 4 lm3886 boards.

I plan to add a switch for a direct line-in, possibly remove the regulator boards from the PS and add a lot of capacitance. I've been running it unregulated (37v) lately. I need to do more testing on reg vs unreg.

I recently hooked up the scope and freq gen to get some spice model verification. Its pretty much right on the money.

OT, but I've found that if there are large pictures in a thread here, I can refresh the url after it has completely loaded, and the pictures are automatically re-sized, with the expanding option available with a click. It's a nice forum feature!

Well the photo is 3 screen widths wide and at least an equal amount high.(I have a 16" screen)
In attempting to view I' looking at a small portion of the photo. With luck I'm maybe looking at
4 components Would like to see the whole photo at once.

I'm sorry but I must have missed that maneuver. Could you please explain how this is accomplished. Thanks..
