I'm pleased with the Belton 9 pin PCB mount sockets used in my ST-35 amp and thought I'd get the same in an 8 pin socket for a SP14 preamp build project. But I can only located ones with mounting flanges attached - well attached, not easily removed. These may not create an interference, but thought I'd ask about simple format PCB 8 pin sockets of equal or better quality to gather alternative suggestions. Thanks
These are decent and inexpensive PCB mount octal sockets -- I've bought a few of them.
