Notes: Explicitly cites the UREI 1176 as inspiration. A second 1176-style 500-series module, 576 Blue Stripe, also exists (separate row) - the two differ in circuit approach (Alter 500 uses a 990-style discrete op-amp; 576 Blue Stripe is a closer Rev-A-style all-transistor design). Price EUR-only (725 EUR).
