EL84 retaining clip
Mounting bracket and spring-style clip for supporting upside-down EL84 valves
Use this bracket and spring retainer to secure EL84s in your amps. I’d definitely consider it essential for amps where the valves are hanging downwards and for those where the valves are horizontal. I now supply this with all Amp Maker kits. It works with standard ceramic 9-pin valve sockets.
Dimensions & info
The base of this spring retainer fits over the valve socket – using the standard 29mm (1.125 inch) spacing between mounting holes – and in place of the metal bracket that you’d normally use. You can use M2.5 or M3 hardware to fix the shield part to the chassis. Place the EL84 into the socket and then swing the spring part up and over the top of the valve to hold it in place.
