Notably this is also pretty well made. This one is rated 220V 50Hz with 150v and 6.3v secondaries so is the most viable candidate for success so far. This is likely to go in my VTVM project.

Also noted that both have 105oC PVC rated cabling and the high voltages taps have double insulated wire on both transformers. Construction is typical EI stacked laminations, copper windings and plastic bobbin. All neatly taped.

Strangely it was shipped from Southall, not that far from me via Royal Mail tracked 48 despite being shipped from China. Must be a drop shipping operation. Good show either way.

Ordered some choc blocks and some power resistors to hook up and will start testing soon (when I get some time which might be a couple of weeks off yet)
