hey teemuk can you throw me a schematic for the sunn stinger 60, I am working on a stinger 20, sound the the preamp is of the same design.
There's a .gif file of the Stinger 60 Rev. B here (3rd post down):

You are correct. According to the User Manual (https://support.fender.com/hc/en-us/articles/115002388866-SUNN-Guitar-and-Bass-Amplifier-Owner-s-Manuals), the Stinger 20 and 60 were the same amp with different power sections. I think even the power sections could be the same, but missing one pair of Power Darlingtons (TIP102 & TIP107) in the Stinger 20.
