Does anyone have any information on this PCA Model 120E FM mono tuner? I recently picked it up. It has 6 tubes. All are either Matsushita or Toshiba so it might be Japanese. There are 2 outputs: high & low. I found one reference on the web to someone selling one on a web site with the original box that says PCA is Photronic Corporation of America. Can't find any additional information. Thank you.
