This is a TRUE SURVIVOR piece at 47 years "young".
In completely stock form, and with everything working exactly as it should.
It looks like we were the first people to ever open it! Very flat frequency response on both line and phono inputs. MADE IN THE USA.
Interesting Feature:
You can plug a power amplifier's speaker outputs into the back of the 3300, and use the front panel to toggle between two different sets of speakers, or play them together (Make sure your amplifier can handle the load that this presents).
Cosmetic Notes:
Light marks on face, sides and top have some scratches, old info etched on back panel, damaged convenience outlet plastic.
Service Notes:
- Front face disassembled, all controls cleaned and lubricated
- Faceplate and knobs detailed and polished
- All functions tested

The SkyFi Process for Preamplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.
At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.
Final testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
