They wouldn't blow. 1amp x 120v is 120 watts. 120 watts going through at 6v works out to 20 amps. Stepped back up, that's an amp out. I don't know of many transformers that can handle 20 amps on a secondary winding, and I would imagine yours is either getting very hot or you haven't powered a large radio with it.
