Notes: ADL states it is 'modeled after and a cross between the vintage UA 175-B and 177 limiter' with added flexibility — FLAGGED classic reference: Universal Audio 175-B / 177 (both mono units); also popularly nicknamed 'little brother of the Fairchild 670' in press coverage (not an ADL claim). Channel count not explicitly stated on ADL's own pages; inferred as mono given the mono UA 175-B/177 lineage — FLAGGED as inference. Tube complement: 1x12AX7A, 1x12BH7A(12AU7A), 1x6BC8, 1x6CL5. Weight 16 lb, dimensions 19" W x 2U x 11-1/8" D. Third-party sources (2017-dated article) cited ~$2,500 street pricing; not manufacturer-published, so price_usd left blank per golden rule.
