This is PCB Layout for descrete SEM type VCF as presented by EFM ,i hve not tested this but can't wait to try it ,the 8 pin sockets are BCM8XX matched transistors ,the idea is to use smd to dip adapters for these ,schematic can be found at fonitronik site ,i ddon't see many people built these descrete vcf's so i don't know if there are any errors ,but i'll give it a try ,the PCB is suitable for 4U format
