You'd need a base adaptor (less nasty than re-wiring the base as they are not pin compatible). I'd have been surprised if ECL11 is cheaper / more available.

The Octal EL33 (= EL3NG) and P8 base EL3N (same order of connections as Y8) are essentially the EL11. The EL11 is a Y8 base. Often the base on dead tube and good tube can be loosened by soaking in warm water (the glue is often wood powder or flour mixed with varnish). Or you can buy or make an adaptor.

I'd leave the radio unchanged and either swap base on tube or use an adaptor. There are other tubes that will work on same g1 and g2 bias.

Hi Aras,
I have more than 20 used EL11 and 2 NOS EL11. If you like to get one, I can test them with my Funke W20.
You may contact me by mail.

Hi Aras,
you got the tubes and I got the money. I hope the tubes work well in your radio.

Greetings,
