I need to find a drop-in replacement for this. It's the PI socket for a 2xEL34 model. Does anyone have a good source? I've done a couple of internet searches and come up dry. Generic tube sockets vary quite a bit dimension-wise and have proven to be a total crapshoot for me in the past, so I'd prefer to get a recommendation from someone who's already been there. I'd really like to be able to keep the shield and its mounting as-is if possible and just replace the broken socket.
