Had I thought of it before installing the sockets, it would be fairly simple to do, however, these pin receptacles already have more mass than those of the original sockets.

"...Two words of warning: make sure that you wind the wire around the pins and then fill it with plumbum. The old sockets had whole where the wires were able to be inserted and tighten before soldered..."

Yes, though it doesn't really look like it in the photo, they are all wrapped at least one full turn before soldering, and in reality the soldering work looks better than in the out-of-focus photo.

"...Another thing: do not use the low temperature soldering metal. Many of contemporary soldering metals have silver in them that lower the melting temperature. If you solder with this easy to use soldering metal then the temperature of the socket pit will eventually melt the join. I had a few times until I learn how it needs to be done properly..."

The solder I used dates from about 1990; I think its pretty old-school stuff, but I'll double check.

"...I have one question to ask. From what I see you changed the wire that goes to filament. Lamm has Brown-Brown/White cable but you have has White-Brown/White. Was any reason why you changed the wire?..."

No, I did not change the wires, just took the photo of the old socket from a different angle (off 90°); you need to mentally rotate the image.
