For sale is a Peerless 4629 SUT. This is a DIY project I made last year and have decided to sell as I will be upgrading to a custom wound SUT. It’s a great sounding unit that is Better than the Altec 4722. with a adjustable turns ratio of either 1:24 or 1:45 with the flick of a switch. It can also be wired to 1:17 if needed. I also installed a ground multi position switch between different grounding connections . I use all top quality parts and wire. Sold As Is and No Returns.

Heres an empty box that can be used with your Altec/Peerless 4722 transformers for moving coil phono step up. As you can see, this has switches so you can use either of the 4722s possible ratios. Low gain will be 1:18 ratio with about 150 ohms loading the cartridge, high gain is 1:36 and 37.5 ohms. This box also has a ground switch to select how the case is earthed. L attaches the case to the left audio shield, L+R attaches it to both the left and right shields (so theyre also connected together). If you prefer to leave the L, R and chassis grounds separated as they come out of your turntable, you can put the switch in the center position and the case will be not be attached to either audio channel ground. In the center position the case still needs to be earthed, so this requires running a separate wire from the SUT to the preamp ground post. In general you dont need to worry too much about what the ground switch is doing, just hook the SUT up however you like, and put the switch on whichever position gives the least hum. This is the same box that Ive also labelled for 4665 transformers in the past, and it will still work with those transformers as well. Ive added a newer box specifically for the 4665, and thats the one Id recommend if you know youll use 4665, or if you might use both.
