Default Re: Are AF11*'s repairable?

My guess is there are a couple of reasons why this works:
1. the heat is applied to the can which is insulated from the Ge and is only applied for a short time and cooled down quickly.
2. there is a big blob of silicon grease over the Ge with a high thermal capacity which prevents the Ge temperature rsing too quickly.

Even so I turned on a radio immediately after cooloing and it was dead presumably from chronic leakage but gradually recovered as it internally cooled.
