Quatre dg-250 amplifier

Hi All,

I recently acquired the above amplifier and have found very limited info on it on the web. I have not hooked it up as of yet. I wanted to have it looked over first. Any suggestions on where to take it? I'm in S. Riverside County (Temecula) and work in San Diego County.

Just wondering if anyone has any info on them. I understand the first models were unstable and were suceptible to "blowing up" (not too sure about that) If anyone can enlighten me, it would be greatly appreciated.

TIA!

Wow that name is truly a blast from the past. I had one in for service a long time ago. It was pretty well built. A lot of room under the cover. Unfortunately, I don't have a circuit diagram for it. I remember visiting Quatre and talking at length to the head of the company but for the life of me I can't remember his name. Big heavy set guy that's all I remember. The amp wasn't bad. That was around the time I was working for a company that made speakers for John Iverson in the San Fernando Valley while going to college. That was a trip!

I would be rather careful what you choose to connect to it as some of those amps were not particularly stable with all loads. They liked to blow up a lot. I would probably keep it between 4-8 ohms. No low or complex impedance i.e. no electrostats or ribbons. Resistive as opposed to capacitive.
Wow an Apt Holman Preamp. Make sure the Apt isn't outputting any DC. If I'm not mistaken, that was a AC (capacitor coupled) preamp.
