The Stereo 300B amplifier, Part 1

Hi!

More new stuff in the pipe line! After several sets of 300B mono block amplifiers it is about time to scale down a bit. Coming up is a stereo single ended 300B amp. These are some of the parts of the signal chassis.




The chassis will be in a similar style as the 300B monos. It will also have a separate power supply. Both amplifier channels will share a common chassis and they will get a common supply in a separate chassis. Output transformers are Hashimoto. The reduction from 4 to 2 chassis does not have enough room for a directly heated driver stage. So I am resorting on an indirect heated tube, the 6SN7.

Updates will be posted as the assembly progresses. Stay tuned!

Best regards

Thomas
