I fail to see how any proerly trained and experienced technician wouldn't know that these are for scan derived CRT supplies...

Firstly, these small transformers are hard wired into the set between the CRT and chassis and are quite small. A transformer designed for 60cps will be much larger.

Secondly, the iso-boost units that were available for sets with 60cps heaters were made with a socket at one end and a plug at the other that matched the CRT, and weren't wired in...

Finally, the seller may not have known what he was selling, and didn't realize the significance of the printed statement included with the units. This is where a properly trained and experienced tech would have been able to see clearly that these are not what he wanted.

My intention is not to offend anyone by this post, but to point out that electronic servicing is best left to professionals. It prevents damage to the equipment as well as the hobbyist.
