Wow! I’m really sorry to hear that Royal Mail lost a P8; that’s terrible! There were so few of them and they are not replaceable.
No, I’m not making anything at the moment; however, there are a couple of stereo compressors in my stock cupboard and I will have a look, see what I have, and come back to you.
regarding the stereo compressor with 2 input gains on the left…. That’s odd. The SC2 V1.05 is a stereo compressor (one of the very first) but it only has a single input gain control. Can you please email me (email@example.com) a picture of the front panel and I can answer the question.
