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

November 10, 200718 yr Author I've ordered a new amp section to go with the power supply More details on the configuration:- Power supply: 2 x 45 sec. Delay Relay tubes per power rail with switch for circumventing delay circuit 2 x 323C W.E. rectifier tubes, 2 x 4B27 Tungar tubes with adjustable loading 6 x Voltage regulator tubes 0A3 types, interchangeable with 0C3, 0D3, 0B3 2 x Voltage Pass Regulator tubes Audio Section: Drivers selectable between Type 27, 6SN7, 15E, 717 and others with adapters Output tubes 6SN7, 6BL7 Inputs/outputs/switches 1 pair RCA input 1 pair balanced input 2 pairs Pre-amp out-RCA and balanced 2 pairs loop out - RCA and balanced Switch between RCA and balanced inputs 2 x Shallco stepped attenuators 45 step 1.5 db per step Heater voltage switch selection Voltage selection Bias selection driver Bias selection output Fixed Bias adjust on selection 1 of bais switch Capacitor bleed tactile button with W.E. 395a indicator lamp/lock thyratron
November 10, 200718 yr 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

November 10, 200718 yr 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?
November 10, 200718 yr 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.
