I have a SA-IIS2 and want to replace the fuses. I removed the three screw from the back but the cover will not budge. Any tips on removing the cover?
Also, what are the fuses sizes, has to be one of the following I guess:
5 x 20mm/0.2" x 0.75”
6.3 x 32mm/0.25" x 1.25”
6.4 x 25mm/0.25" x 0.98”

Finally, the cover is off. Facing from the back fuses are on the right side. near the copper cylinder.

Size for all the fuses are 5 x 20mm/0.2" x 0.75”are
