The technical curator
Identifies, measures, compares, and evaluates electrical behavior. Records test conditions, uncertainty, stability, and the limits of each result.

Curator’s Handbook
Care, evidence, and judgment turn an object into a preserved history.
The curator is a steward.
A curator accepts responsibility for understanding an object and preserving its story. The work includes care, testing, research, listening, documentation, and judgment. Building is one part of that responsibility; the record must remain useful to the next person who encounters the specimen or instrument.
Different forms of attention
The historical curator
Studies markings, manufacturers, sources, and previous service. Preserves provenance and distinguishes documented history from a plausible explanation.
The musical curator
Plays and evaluates voice, texture, articulation, dynamics, and response in a recorded musical context.
The listening curator
Brings experienced attention to what can be heard, noticed, and compared. Useful observations do not depend on being a builder or performer.
These are complementary perspectives, not ranks or credentials. One person may contribute several. Differences in interpretation remain in the record rather than being forced into agreement.
Care begins at arrival
Record incoming material under its numbered OCA acquisition, including source, location, date, lot contents, and the questions it raises. Separate acquisitions may share a date. Photograph markings and condition before handling obscures them; organize storage so identity remains attached to the object.
Ordinary supporting stock such as modern resistors, LEDs, and diodes may remain documented under its parent OCA and organized working-stock location. Individual OCS identity is assigned when specimen-level study or placement warrants it.
Test with a purpose
Characterize the properties relevant to the intended decision. Transistor observations may include type, lead identification, gain, junction voltage, and leakage. Capacitor observations may include marked and measured value, physical condition, ESR, and leakage where appropriate. Record the instrument and conditions alongside the result.
A single analyzer screen is evidence within an evaluation. Reliability and suitability require the observations relevant to actual operating conditions. Preserve measurements, repeated checks, comparison context, and unresolved questions.
Keep observation and interpretation distinct
- Observation
- What was seen, measured, or heard.
- Hypothesis
- An explanation awaiting testing.
- Validation
- Repeated evidence sufficient for the decision at hand.
- Unknown
- A legitimate archival state, carried forward without invention.
Describe musical behavior with its circuit, bias, player, and listening context. Preserve the curator’s reflection alongside the evidence while making its interpretive nature clear.
Document three connected histories
- OCA · Acquisition
- The numbered arrival record: source, date, location, and lot story.
- OCS · Specimen
- The permanent individual identity, photographs, characterization, condition, storage, and role history.
- OCI · Instrument
- The individual build: Family, Formulas, collection, revisions, linked specimens, bench and listening results, photographs, and service history.
Acquisition is distinct from accession. Accession is the institutional threshold into the permanent specimen archive. Physical accession cards provide quick reference; digital records preserve the detail. Link OCS and OCI records in both directions when a specimen serves in an instrument.
Condition and role answer different questions
Electrical condition: Viable; Compromised but functioning; Dead.
Collection role: Available for placement; Placed; Retired for conservation.
Unverified material is still awaiting sufficient evaluation and accession. Conservation, retirement, or documented deaccession preserves the record. When a specimen is removed from an instrument, its previous service remains part of both histories.
Every measurement is an observation.
Every observation builds a specimen’s story.
The curator’s commitment
I will observe before concluding. I will measure before assuming. I will preserve before discarding. I will document what I learn so others may build upon it. I will honor both the engineer who first created these components and the musician who may one day give them a new voice.
Status may change; history does not.
