New model of BG7TBL noise source

Do you mean this one? Havn’t tried it but is still pulling around 160ma, maybe a bit less than the older BG7 ones but it is still going to get fairly hot.
I have one of the origional BG7 here that has had quite a bit of use over the last 6 months and is still going strong but they do need a fan mounted to the board.
