I've had some Rod Elliott MM RIAA pcbs PCB's made up . The pcb design was done by a Russian guy who was restoring his turntable and can be assembled so as to be fitted inside a turntable , or not , depending on what you want to do . Low noise adjustable power supply pcb utilizing LM317/LM337 . The phono boards are dual layer boards with solder masks on either side and the PSU boards are single layer with solder masks on either side .
