Here's a (DC coupled) grounded cathode followed by a White cathode follower:

A few guys on diyaudio have been messing about with cardboard exponential horns for ipods, which I thought was an excellent idea coming out of left field as far as I was concerned.
You might like to take a...
Yes, thinking about it, that's correct.
If these were 8-bit numbers, you'd want
1000 0000 (-128) to become 0 (0000 0000)
1111 1111 (-1) to become 127 (0111 1111)
0000 0000 (0) to become 128 (1000 0000)
I would think you could build a finite state machine in TTL logic running off the bit and word clocks to do this.
It'd be easier implement it in a CPLD but I doubt you have the resources to accomplish this. You'd need to...
I don't like to see a poster get ignored for too long.
It's nice to hear you found the problem with your amp after so long a time.
Many years ago I built a stereo amplifier based on one of the...
