Hi everyone,
I've been in the process of restoring my old SDSV brain and had a couple of questions.  Firstly, I was wondering if anyone had a pair of rack ears for it, or would be willing to fabricate a pair for me.  Secondly, I've notice the output of the brain is fairly quiet and was wondering if anyone else had run into the same problem, and if so, how I can fix it?  

Thanks,

chris
