I think you are going back quite a few years, since according to one person, Mel Hodes died at least ten years ago. He was very knowledgeable, though, a sincere dealer with a good ear.
Larry helped me update my PAC Pro-Reference II power supply about 7 years ago and was extremely helpful and did great job.
I am still using it in my main system. They are designed to use Telefunken smooth plate 12AX7's throughout and after trying other combinations Larry's voicing is correct. Use those tubes and the sound is magical. I have a 1984 model with the outboard power supply and it is fantastic.
