Socket savers for tube amps and preamps

So I purchased some socket savers for my pre-amp many months ago. I have a Schiit Freya Plus and because the sockets are about 1/2 inch down inside the casing I had purchased the socket savers to bring the base insertion point up level with the top casing of the amp. It was a recommendation because I swap NOS tubes periodically and it’s not always good to put pressure on old glass, better to handle tubes by the base. I developed a hum and thought? it might be a bad tube but low and behold the socket saver cracked and broke at the key way. Lol

Does anyone in tube world know where I can buy quality tube socket savers? Does anyone use these? BTW the hum is gone now that the broken key way has been removed. Who knew?
