Has anyone used or have any experience with the QSI Quantum Engineer Controller add-on sound system, especially with DC and not DCC control? I have an MRC Controlmaster Walkaround throttle, and was wondering if it is possible to use or adapt this to my throttle? 

Ok, here's my dilemma: 

Still running DC.. 1 block - 1 engine operation on a small layout…

I recently installed a Micro Engineering turnout. Unbeknownst to me, the through track of the Left turnout, leading to a spur, is dead after the frog. The frog is double gapped on both sides of the frog. I have feeders soldered to the tail track that provide power to the through track and diverting track. There are also two feeds on the other side of the diverting track. Please see diagram:

As a child in the early fifties I got my Louis Marx G scale train set. It has set unused most of my life, following wherever my military career took me, then sat in my closet for the last 23 years. A discussion about Hal Joyce, TT scale, and his starting HP products in my small hometown got me to pull out my train set.

I am beginning to expand/improve my current layout. I want to add more overhead lighting, scenery lighting, etc., and powered switches. I currently only have one outlet (20 amp) servicing my DCC bus work, 2 overhead fluorescent lights, and my home furnace! So I definitely need to put my layout on a separate dedicated circuit and add 4 or five more outlets around the layout to prepare for these future enhancements.
