Joule Electra VZN-100
Documentation on the Joule Electra VZN-100 is thin. The one solid trace is a line in the annual amplifier directory in Audio (October 1998, p.80). It lists the amp at $9,500, well above the VZN-80's $6,900 in the same table.
That same directory describes the VZN-100's circuit in shorthand, referring back to the VZN-80: a single-ended, output-transformerless (OTL) amplifier with a differential mu-follower driver stage. The surviving row also shows "100" in the output-power position, matching the model number. Beyond that, the record goes quiet. No measured review, no manual, and no clean run of specs has surfaced in the archive.
Known from the Audio directory listing:
- List price: $9,500 (October 1998)
- Topology: single-ended, output-transformerless, differential mu-follower driver stage
- Listed alongside the VZN-80 and VZN-160 in the same directory
