Notes: Two-channel (dual mono) all-tube mic preamp; tube complement 1x12AT7A + 2x6922 per channel. ADL's About/timeline page lists a 2003 joint venture with PreSonus for an 'ADL/PreSonus 600 Stereo Tube Preamp' — year_intro reflects that timeline entry; unclear if identical to the standalone ADL 600 currently listed on adl's own product pages (FLAGGED as inference/ambiguity). Country of manufacture not explicitly stated on the ADL 600 pages (other ADL models explicitly say 'Handbuilt in the USA'); left blank per golden rule rather than assumed. Price not published by manufacturer; a secondhand mention cites an original ~$2,000 price-point target from the designer but this is not a confirmed current MSRP, so left blank.
