I it also good to remove the glue if possible the ones sansui uses are corrosive over period of age.Yes the glue helps in damping and securing them caps. As this amp is fully direct coupled n has a ultra wide frequency response, it is important to damp all undesired vibrations. So the gluing big caps is engineering choice.
Shipping was 19000 JPY with enforced double box packaging. After fully packed it weighted a hefty 26.5 kgs.
You can remove it easily but de-solder components before removing it, the glue eats resistor legs easily , and i had to replace few resistors as well.
