December 6, 200619 yr comment_21980 I only have a rough daswing at present. So the power supply is using the high power rectifiers with the plate caps? Report

November 10, 200718 yr comment_63122 Looks like the PS that is almost done on my new Maestro-XLR preamp. I wonder if they are the same tubes? It uses the same tubes that are on the Enigma box Mikhail made for Synergestic Research cable Co. If you dig up pictures of the RMAF this year (singlepower or SR room) your can see the tubes. They are about the size of lightbulbs. I am going to be using the 6sn7s in front 6bl7s on the amp section. Here is lionk to the rooms. http://live.audiogon.com/events/rmf2007/intr/intro.html Report

November 10, 200718 yr comment_63130 Rob, My amp section is done and Mikhail is close on the PS. I will send(email) you some impressions and pics if you would like? Report
November 10, 200718 yr comment_63178 From my understanding that is a prototype and the finished product will look a little better. I guess the guys at SR cables are very happy with it. Cant wait for preamp to get here. Mikhail sounds very excited about the power supply with those tubes. Report
