Thanks for all the suggestions. My St-120 came out sounding and looking beautiful! I have my Rogue tube phono pre-amp and now this ST-120 together is more than I hoped for in sound. I may need to think of the tube pre-amp now to complete the whole musical chain. I had the case and transformer covers powder coated. I would like to find out how to integrate my systems 12v power on/off signal into the ST-120. I made some changes that I wanted that worked out perfectly. I was going to put digital meters in the front bias holes. I even bought a voltage regulator and 2 digital gauges. But I couldn't see how to make it work and not introduce extra noise into the ST-120. I am sure there is a way and some one much smarter than me figured it out. I added LC-1 shielded cable RCA Inputs to the rear and put in a switch to give the ability to choose either the front or the rear. I put the power switch up front. I put nicer speaker out posts and a switch to select either 4 or 8 ohms. I made a double shielded power cable and a ground through a switch to either be grounded or not. The shielding is connected together to the ground on the wall outlet. Inside the case I have the shielded ground on the switch to be connected or not. I cannot notice any difference in sound between grounded or not though. I do like my power cables double shielded still. I installed 2mm posts for checking bias near the Driver Board pots. I installed a switch to control the rectifier delay board for tube or SS rectifiers. I can toggle on the switch between rectifier types without having to go inside. So far I have only used tube rectifiers but have a SS on standby. Whew, if you made it through all of that rambling , I am impressed. Thanks again to Bob for answering my novice questions and others for posting things that they did to their ST-70/ST-120. I am VERY HAPPY with it!! Thanks Scott Moore
