Take a look at this photo:

https://www.vintage-radio.net/forum/...1&d=1277330178

The two valves to the left:

The uppermost should be a UCH42

The lower one should be a UAF42.

The row of valves to the right:

The uppermost should be a UY41

The next one down should also be a UY41

The next one down should be a UL41

The next one down should also be a UL41

The bottom one should be a UAF42

So far as I can make out:
