Friends who are interested in making a high-quality Posh Pul to listen to music, you can make this amplifier and enjoy its sound. This is a serious task in competition with expensive brands. As long as you respect the quality of the parts, the result will surprise you. PCB assembly is not used.

Is it working, or still being assembled? Is the schematics yours, or copied from an existing product or DIY project?
If it is working, have you measured it? What is the output power, THD, etc?

It appears that the damper diodes are only being used for soft start purposes,
since the UF4007 diodes do the actual rectification.

I agree with @rayma. In your schematic the UF4007s do the rectification. The current is then guided through the damper diodes to provide “slow start” as well as whatever “signature” and filtering of spikes the damper diodes imparts to the rectified current. Capacitors follow the damper diodes.
Please rotate the picture of the schematic for easier viewing.

Shindo montille 6v6 power supply. In this amp we can see capacitor 47mf in rectifier diode.why ? In el34 power amp not use cap in uf4007 .our frinds who has damper diodes aske circuit for use them . ... use in power supply not rectifiction. But it is not only for soft start .... Ok ?
