My friend Mario Ribaldi ) has written me with a question
about restoring tube radios. Can anyone help him?

Mi amigo:
Me restore project of radio Geloso 217 is begun. I may ask how to restore valve
activation (what you Americans call tubas) for no strong emission. I find
website that American place tube in specail place. Can this help restore
activity? The report is from SURGERY MAGAZINE by Doctore Dabid Busch in
Wisconsin, Madison.
