The New 6CB5A Amplifiers

 Hi!

Last month I showed the initial construction steps of the new 6CB5A amps. In the meantime they are finished.



The amplifiers are constructed in tower style with dark wooden enclosures.



The amps are laid out as mirror images of each other.



The tube complement consists of a 6N7 driving a single ended 6CB5A wired in triode and a full ave bridge of 4 6AX4 diodes.




This yields 8W of glorious single ended power. Output taps are available for 4, 8 and 16 Ohm speakers.




Here a photo of the naked amp without the enclosures showing the vertical assembly technique:




The amps will now test run for a few days before they are shipped to their new owner.





Best regards

Thomas
