Hi. I just purchased a used HRD Portable Amp (sans DAC). The handwriting on the label, on the bottom, isn't completely legible. I think it says "2/1/07" and "211206." It came with a brick PS (model APS48-ER-125) that connects via a 5-pin DIN on the back. It also has a 5VDC "battery" jack to recharge the internal battery. The package didn't include an adaptor for this jack.
I've been running the amp via an Astrodyne PS for over 3 hours and find that the battery isn't recharging. I have the "battery power" switch in the "off" position while the DIN PS is engaged.
Question 1: Is the battery dead?
Question 2: Will I need to get the 5VDC recharger to charge the batteries or should the batteries be recharging via the DIN PS?
Question 3: Am I losing any SQ by running the amp via DIN? Or put another way, does the dead battery affect the SQ?
Question 4: The amp didn't come with a manual, and I couldn't find one on the HeadRoom site. Is one available? (I did find the manual for the amp + DAC combo.)
I've always wanted an HRD amp only unit and I was happy to find this.
Thanks in advance for any info you can provide on this "rare" amp.
