Hello -
    This is Byron, WA5THJ.     I used to be somewhat involved in rebuilding the receivers but due to work and family I had to drop out of actively pursuing the sets. 
    I am looking for the person who needs Collins R-390A modules.
    I was wondering if someone would be willing to do a trade:
        1. My good condition Collins R-390A RF Tuner / Crystal Osc. module pair for a nice 1967 EAC RF Tuner / Crystal Osc pair. 
        2. My good condition Collins R-390A IF module for a nice1967 EAC IF module. Mine has a good 3TF7 on it.
        3. My good condition Collins PTO for a nice Cosmos PTO. As of now my PTO has 3.5 KC. of end point spread, do you have a nice Cosmos equivalent or less?
        4. My Collins front panel tag for a 1967 EAC front panel tag.
    Here is the story - I bought a good condition receiver recently that is a 1967 EAC mainframe, but it has the Collins front panel tag, Collins RF Tuner / Crystal Osc. module, Collins PTO and Collins IF deck. The receiver works well on all bands and all filter positions. 
    I would like to restore it to original all EAC modules. I thought possibly someone may benefit from the Collins parts. I would like to do a straight trade module for module. I do not need fully restored modules but nice working ones that may need just a little polishing up. I will leave the tubes, crystals, plug in crystal heater and 3TF7 in these modules if we do the trade.
    Thank you for the consideration. 
                                                                            Byron Tatum WA5THJ
