Anyone out there know of a computer program that I can use to test an external DAC of my own design? USB to S/PDIF adapter? Individual frequencies for harmonic distortion tests. Sweeps for flatness tests. Multiple frequencies for I.M. distortion tests. Variable amplitude outputs for linearity tests.

I posted earlier about this Melos preamp. I now have it on my bench (not working) and it seems to be missing a part, possibly a power regulator. Does anyone out there own an MA-111 that would be willing to pop the top and ID the part? Let me know and I'll send you a photo of the board.

I've just come into possession of a beautiful pair of PSB Image 4T speakers. Its a long story but they were shipped via UPS Ground in a pretty sketchily packed box and, surprise surprise, I now have a problem.

On one of the speakers, the mid-range speaker seems to be damaged. The sound from that one mid-range speaker is very bad. I guess I have to replace it or get it fixed. The problem is that I don't really know where to start on this project: where to look, what to expect to pay, etc.

I would greatly appreciate any help.

Best,

Aktrop

For the record:
I've read every single one of your many posts, and this, more than ever, sounds as though you're describing yourself, DUP.

Hello,
I recently picked up a used equalizer, and decided to hook my turntable up to it for a better sound. However, when I run the turntable through the equalizer (a Pioneer SG-9) to my receiver (Sansui G-8000), it produces some hiss when the volume and considerably more hum than when I had the turntable connected directly to the receiver. Any ideas on how I can correct this problem? Thanks!!
