I noticed today that there is a new version of the popular BG7TBL noise source dated 2016-02-06. Prior to this the most recent version I had seen was 2014-08-20, and those often had a limited life span due to excessive heat. There are many of the usual Chinese vendors selling this new model, as well as many still selling the 2014 model.
The amplifier chips appear to be different, and the new one doesn’t have the electrolytic capacitors like the old one did.
I’m curious if anyone has tried this new model and found any improvements, and if anyone knows what the amplifiers are that replaced the three ERA-5+ chips used on the 2014 model?
