2002 40th-anniversary stack built around two 50W JTM 45/100 style heads.
Marks that can be entered for this maker: Serial number (plate), Transformer code, Speaker code, Born-on / QA sticker, Panel features (no code).
Nothing predates 2006; components only push the date later.
Sold-price aggregates are not collected yet, so the archive gives no figure — condition, originality of the transformers and a documented recap move this model more than any list price.
