They are in need of Power Supply revamp, but I sang on this one in Syncron Studios in 1965 in Waallingford, CT.

I want to sell them. Can you provide any advice how I should do it and what they are worth. They are in near excellent condition. The batteries have been removed so there is no leaking mercury batteries. They are still in the original wooden boxes.

Many mercury batteries are replaceable with an equivalent cell. The whole thing was an example of environazism anyway, the mercury cells were quite recyclable and in event there is naturally occurring mercury everywhere.
