Re: Two stage differential amp ?? on NFB

Hi Pipo,

My amp uses ideas from this forum and around the web so I don't have anything new. The CCS's are a cascode pair of DN2540's set for somewhere around 85-90mA for the output pair. I used one of Gary Pimm's battery biased CCS designs for the 6BL7 differential input stage. I did use a small/medium sized heatsink on the output CCS and I haven't had any trouble for nearly 2 years so far.

Send me an email and I can send you some schematics.

Regards,
John
