The following pages represent various "factory recommended" adjustment procedures that apply "generically" to virtually all H.H. Scott vacuum tube amplifiers.

Note: Due to product evolution not all amps feature the exact same adjustments, test points, and measurement procedures. If you are unsure of your particular application, consult a qualified technician or post a question on the Vintage H.H. Scott Hi-Fi Web Forum.

These are "final" adjustments. Before attempting to perform these procedures, (particularly critical Bias and DC balance adjustments), you need to have completed troubleshooting and restoration of all critical components described elsewhere within this publication. Otherwise you'll be a lot like the proverbial dog chasing its tail.
