Thanks for sending the photo. I own a 380s and there are a couple of differences. The main differences I see are the following on the 380s:

- input opamps are opa627
- output bjts are mat02 and mat03
- there are different resistors / more precision around the input stage
- there are different film capacitors again around the input stage
