Chapter 20

Technical Reference

Schematics, troubleshooting guides, and calculations for the Electrocompaniet amplifiers — the true EC factory designs, plus what came after: my own NRF-era (Norsk Radiofabrikk) modifications and personal work, kept clearly separate below.

Electrocompaniet

See Post-EC / NRF for what came after — not EC factory work, my own modifications and designs from the NRF era (1979 onward), kept separate in the menu on the left.

Not ported: distortion_calculators.htm and SingleCalc.htm (an ActiveX distortion-calculator control — only ever worked in old IE, and the control binary itself isn’t something to carry forward) and a_strange_one.htm (linked from the old site as “a further schematic variant”, but the actual page content is just a generic “site under reconstruction” placeholder — no real schematic survives there).

One gap filled in during migration: the old site’s schematics page said “SCHEMATIC 5 is coming later” for the Special Version schematic and never delivered it, but the scanned image existed unlinked in the old site’s files — it’s now included on the NRF modifications page.
