This is a custom tube line stage preamp made by Oliver J W Sayes (aka sonic_oli) in New York. The huge (24 lbs.) separate power supply uses a 5Y3 rectifier. The preamp uses 6SN7’s and either type 76 or 37 tubes. No adjustment is needed to switch between the 76 and 37, just swap tubes and go. The volume control is a TKD 2CP-2508 Series Stereo Volume Potentiometer. Upgraded capacitors are Jupiter copper foil wax & paper capacitors. This preamp has 4 sets of inputs and 2 sets of outputs. As you look at the photos you will see the stereo volume knob on the left, the 4 input selector in the center and an unused knob on the right. That knob is there because the original design called for separate right and left volume controls, but I preferred the upgrade to the TKD stereo volume control. The power cord linking the power supply and preamp is 38” long, so they don’t have to be located side by side.
My all-time favorite preamps have used type 76 tubes. I find them to have a great combination of richness, detail and solid imaging. This particular preamp was made for me to go with the Korneff 45SE clone amp made by the same maker. The 76’s can be replaced by 37 tubes with no adjustment needed. The sound of the 37 is sweet, clean and almost ethereal. The variety of sounds available by switching 6SN7’s, 76’s and 37’s give it an unusual ability for you to tune it for your taste and system. I am including two complete sets of tubes with the preamp. 5Y3 – Tungsol 5Y3WGTA, Sylvania 5Y3GT 6SN7 – Pair of Sylvania (marked Philco) 6SN7GTB, pair of RCA VT-231/6SN7-GT grey glass 76 – Pair of National Union 76, pair of GE 76 37 – Pair of Sylvania 37, pair of Cunningham 37
I have many more of these tubes if the buyer would be interested. I am not selling these beautiful sounding pieces to buy something else. I am forced by age and physical condition to sell all my cool audio stuff. This great gear needs to be passed along to those who can use and appreciate it. Dimensions – Power supply 24 lbs. 12.5” W x 9” D x 8.5” H, Preamp 9 lbs. 12.5” W x 9” D x 7.5” H
