Line 6 Spider Jam circuits needed please

[Brian Swatton]

Got one of these on the bench at the moment. Main power amp fault is repaired, but now no HF out. The 2030 is ok, I believe Q1, on its input, has b-e s/c. I've been trying to track down the device code "GR" but haven't found it yet.

I've got circuits for the Spider 212 and HD75 already, but neither covers it.

Any useful info appreciated.
