One of these radios found a home at my house yesterday. I am typically a collector / restorer of tube based radios, but have had a couple Harris RF-590's and a Watkins Johnson. I am familiar with digital circuits (I've been in the electronics engineering field most of my career) and know my way around an O'Scope.

I have directly emailed Gary the following but thought I'd post to the group as well.

1. Radio is populated with "VLF" Eproms and an assortment of filters.?

1a. Battery was changed (now dead) says 3.6v but manual says 2.4v. What should I replace it with?

2. The radio powers up, voltages at the power supply are good, but there is no front panel response. Small LCD shows two digits in upper right corner, Freq LCD shows random numbers that don't change, but can be different after power cycle.

3. The three OOL LEDs are lit on the A9 card - obviously pointing me to some phase lock issues.

4. There is 15v at the LCD lamps but they are not on. I can't imagine they are all bad. Unpowered there is 100 ohms across the lamp circuit so seems like some / most filaments are intact.

5. The Silver backing of the LCDs is discolored - are replacements available?

6. Where is a good source for spare parts?

7. I expect I'll have to go through and replace many, if not all, of the tantalums like I had to do on the Harris radios I had.

Any direction is appreciated.

Tom?
