Hi, i have been snagging microwave transformers from the dump for quite a
while and have a rash of all different ones too. I considered setting up a
website just so mot collectors could trade to get a matched pair. my network
expertise is horrible so never was done. I had 5 of the same oven made in
the same year,same model with 5 different transformers!! cul brian f.
