Thanks Chip !
I don't have the early Valoy, only the Valoy II and that one's condenser certainly looks like it is from the same family.
But the condenser of the Valoy II is quite different from the Ic's condenser: mostly because you fix it in from below using a bayonet. Many Valoy II owners are not aware of this and remove it from above, taking out screws and a ring. All you need to do is push up the condenser, turn it a bit and let it drop in your hand. Putting it back is just pushing it up and turn it . . .
With your older Valoy, how is the condenser installed? If it is not too much hassle can you show me a picture of this condenser? No problem if you can't, I can ask someone else too.
