Depending on the type of valve radio, it may be possible to convert it into a bluetooth speaker. There are some different options:

1.  Use the original speaker and valve circuitry. It will sound the same as the original radio.

2.  Install a modern amp and speaker. The sound will be better than the original radio.

3.  Install a modern amp to drive the original speaker. It will sound slightly better than the original radio.

If one of these options interests you, email me photos of the radio and I will let you know what is possible.        email: james.justjazz@gmail.com
