• Ross Compressor PDF project file from GEOFEX

Please Note:There are errors in the GEOFEX PDF file.

• C2 should be value of 220pF, the parts list lists it as 0.0022uF (2200pF).
• C11 should be value 0.001uF instead of 0.01uF
• C12 should be 0.01uF instead of 0.1uf

The values listed in the PDF file for C2 and C11 will cause a substantial loss in treble sounds. Trim pot is 2k value.
