Sherwood's integrated valve unit, remembered for build quality at a price below Fisher and Scott.
Valve receiver/unit: HT rails stay live after switch-off and the original can electrolytics must be reformed or replaced before power-up. Output transformers and the faceplate are the value drivers; history of a professional restoration usually adds more than it costs.
Marks that can be entered for this maker: Model / catalogue number, Model / catalogue number, British capacitor code (Hunts, Mullard), Japanese capacitor code (Nichicon, Chemi-Con, ELNA), EIA component code.
The introduction year is not documented, so the model narrows nothing.
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.
