Hi Guys,


Is anybody able to suggest where I might find good quality octal sockets?


Nothing is available locally.


It doesn't appear as though they are available from any of the standard reputable suppliers eg: Mouser, Farnell, Digikey etc.


Has anybody had any good experience with the stuff available on ebay?

I have used these Belton sockets and liked them very well - nice, tight pin grip that allows many reinsertions. The pins on these “so-called PCB sockets” (they look like chassis mount sockets with long legs) are unusually long and allow flexibility in dimensions of the pin circle.

BTW, where is DIY Hifi Supply physically located? I could not find any indication on their website.

I don't like a lot of screws on the chassis tops, nor do like flexing of the pc board inserting tubes. So I found this, it has pcb pins but it also has a chassis mount flange. So basically the whole pc board is supported by just mounting the tube socket the old fashioned way. No flexing of the pc board, fewer screws showing on the chassis top.

To add I'm just learning how to make pc boards, I'm putting all the parts on one side and tubes on the other side, allowing usage of a socket like this. Basically any part I want sticking out externally goes on the tube side, like a heatsink, led, meters, etc. All parts residing inside the case mount on the other side. So the chassis is basically holed out for whatever parts need to pertrude and don't have to worry about clearance because all passive parts are on the other side. I have always avoided buying peoples pc boards where they have the parts all on one side. My tube side is largely a big copper pour ground plane.

Cool, to an extent though depending on the gap left between the chassis bottom and the tube side of the PC board. With these sockets you have a half inch or so, so resistors, small caps, etc can be on the tube side. So yes some of that tube side real-estate can still be used for low profile parts. I made my tube side largely a copper pour so I bring the twisted filament right to the tube with via's across that tube side. That way the filament wires are against a ground plane side on the approach to the tube, rather than bringing those into the components side where more things can pick up hum. My filament wire is basically then surrounded on the top by the chassis and on the bottom by all the tube side ground plane'ing going on there, like a filament wire sandwich..
