Socket hole cover
A simple push-fit plug to cover unused 8 and 9 pin socket holes
If you’ve bought a chassis punched with more holes than you need, these socket covers are the perfect solution. It’s a simple push-fit cover and fits holes that have been punched for 22mm 9-pin or 28.5mm 8-pin valve sockets.
Dimensions & info
The 9-pin type is suitable for holes of approx 22mm diameter (this means that it is not suitable for use in those vintage amps that used 3/4inch holes and sockets for preamp valves). The 8-pin type suits 28.5mm diameter holes.
