[CVRC] help locate?

[John Ryan]

Hi,
 
I have tried all of the usual Web sites and links to no avail. I am in need of the following two items;
1. a service manual with tube data base updates for a Hickock Model 539-A tube tester
2. a schematic and/or Ryders publication for a Zenith "Universal" AC-DC portable radio.
    This is similar to the 5G500 chassis. The tube line up is a 1LA6, 1LN5, 1LH4, 1LB4, and 
     117Z6. The s/n of this unit is T 295132.
 
Thank you for your assistance,
John, W7KEZ
