Thank you willis, but I didn't find them. They found me. It all started with a blown rectifier, and a seemingly bad episode. I'm mystified by it. I have tried not to make any assumptions, but it would seem that they are very rare.
Haven't heard the final word yet, but I don't know if he has more available right now. Just have to wait and find out. I just wanted to share my good fortune with the community, as you all have shared so much.
Of course, I enjoy a-lot of poorly-recorded 30's & 40's mono material .... so I need all the help I can get.
