Sometimes you just want to know whether something is working, and how well, to help you decide whether to service, buy, sell, etc. We offer a condition report service: an evaluation and written report on the current performance of any pre-amplifier, amplifier, active crossover, or tuner, for your information. We perform a visual examination, graduated power-up, and measure as follows:
- THD, IMD, bandwidth, RIAA accuracy, output level, all inputs and all outputs.
- Power amplifiers
- THD, IMD, bandwidth, stability, total power (up to 200W only).
- Active crossovers
- Gain, THD, IMD, crossover point(s), output level.
- RF sensitivity, quieting, THD, IMD, audio bandwidth, FM de-emphasis accuracy, stereo channel separation.
This service can be done while you wait and is priced per functional unit, i.e. double for integrated amplifiers (preamp+amp) or triple for receivers (preamp+tuner+amp).
