Hi All,

On the Vox AC30 C2 combo, when swapping in some new valves there are some small plastic sleeves which hold the valve spring clip to the tip of the valve. One or two of these are somewhat stretched and need replacing as they just drop off. I cannot find any reference to them online and was considering using heat shrink sleeve instead, but I am concerned whether heat shrink would stand the high temperature of the valve. Any help would be appreciated.
