Title: Schematic for Stinger 60?
Post by: Krwkka on January 30, 2013, 01:58:36 pm

I've just inherited a Sunn Stinger 60.  I'm quite surprised at the tone of this little monster  (in a good way!), but I want to recap it and maybe make a few tweaks while I'm in there. Does anybody know where I might find a schematic or service manual for this amp?

Thanks!

The attachment folder on this site is full.

I have posted the schematic for the Stinger 60 at this site: http://www.ampix.org/index.php .

I have no idea if you have to join to see files or how to find them. Look for a Sunn folder.

Here is the schematic. The input stage is a JFET with a servo to set the operating point followed by an FMV type tone stack. Next are two CMOS gain stages and then Reverb and a power amp. The power amp has no short circuit or SOA protection.

Necro bump!  I'm looking for a Sunn Stinger 60 schematic and the file on ampix is down, anyone mind re-uploading it or sending it to me please? I promise I'll hang around here instead of lurking so much :)
