Info

Mixed job-lot of 1970s Swedish Radio (Sveriges Radio / “SR”) broadcast console spares built around SR’s own discrete op-amp blocks (HA70), with early Lundahl “SR” series transformers (SR501 etc.), plus a handful of faders and some Cadac modules in the same physical Euro-format.

Lundahl’s SR-series were developed for Swedish Radio around 1970, and SR501 is a line/isolation transformer still documented by Lundahl today. The HA70 is referenced in Swedish hobbyist forums as SR’s in-house discrete op-amp (“diskreta OP-ampen HA70 som SR designade”).
