In my TV business I replace quite a number of transformers, but to date I have tended to discard them. If there is demand I could save them. With modern split diode line transformers the ferrite core is frequently not very easy to remove and so may not always be useable. In the old days it was much easier! Not much activity here this weekend. Strong winds were causing the resonance of the loop to change resulting in dangerously fluctuating SWR. But there appears to have been little activity anyway.
