Sunn Concert Lead Silverface reverb tank

[Emilio]

Hi everybody,
I have a Sunn Concert Lead Silverface with the reverb tank missing.
I have been looking for informations on this reverb tank on the web, but didn't find anything.
I need to know the Input and Output impedance of the tank to look for an equivalent replacement.
If anybody have these information it would be a great help for me.
Thanks
Emilio

I don't have that information. If I come across anything, I'll let you know.

Good luck.
