About the Iron-Coupled DHT Line Stage
The ToolShed Amps Iron-Coupled DHT Line Stage is a transformer/iron-coupled, directly heated triode (DHT) line preamplifier. ToolShed Amps lists multiple tube configurations: the original version uses 01A driver tubes and 71A output tubes; a European-tube version uses RE084 drivers and RE134 output tubes; and a newer V2 version uses 101D driver tubes and 205D “Tennis-Ball” output tubes. The design emphasizes transformer coupling and the resolving character associated with thoriated-tungsten DHT tubes. Publicly available information describes the tube variants and design concept but does not provide a complete standardized data sheet covering all electrical, physical, and connection specifications.
