Here are two well regarded British design phono stages, both knock-offs.The first clones the circuit from the Creek OBH8-SE which has the j-fet input.I bought this from the eBay seller PCB Audio a few years ago. I opened it once to verify that it had the j-fet and it does. I havent opened it again. One note; there is a delay of a few seconds at power on, the led will glow when its fully on. The second is a copy of the phono section from the Naim Nait integrated amp. I bought the bare board from another eBay seller, Jims Audio. I populated it with quality parts from US, Japanese and European sources. Its housed in a small generic enclosure.Also included is a 24vdc wall wart to power either one Both operate as they should with no weird noises or hum.I had fun sampling these two different approaches to the same end. Guaranteed as described. Will be carefully packed and promptly shipped. Standard shipping
