A few weeks ago, I dropped off my 752 for a checkup. I've had this amp for many years and felt like it was time to have it gone over. Based on the serial number, it was built in 1988. Despite the age of the amp, it still bench tested very well. After it was all put back together, it produced 91 watts per channel into an 8 ohm load.
The amp was dissembled, cleaned, and tested to leave nothing to chance. All the capacitors, including the main filter caps were replaced. The main filter capacitor are a little shorter than the old ones, but still look "right" as they do protrude up through the chassis and are the same width. New LED lamps were also installed. One very slight modification was the addition of a power switch, along with a fresh power cable. The on/off switch looks clean and replaced the aux power outlet that has always gone unused.
Overall, I could not be happier. The performance is better than ever, and the new filter caps really helped tighten up the bottom end. I've always really liked the direct couple amps and the industrial look of the 752/754.
Audio Exchange, in Atlanta, did a fantastic job. I can't recommend them enough if you're in the Southeast.
