Hammond 290 series power transformers

Since my last build a few years ago Hammond has released some new power transformers targetting the guitar crowd.

I'd not seen the 290 series previously and I wonder if any of the esteemed members has experience with these and has compared them to the 300 series.

There are some models (e.g. the 290CEX) that offer me some advantages in my yet to build amplifier. The power supply is in the last stage of collecting parts.

Thanks in advance if you share your experience / thoughts.
