    I recently acquired a very nice D&A Phantom 500 amplifier in an estate sale. I realize that this is a poor amplifier for any RF work these days, but wonder about the value of the twelve Sylvania 6LQ6 tubes. Looking on eBay, there are over a dozen listings for this tube, so I would like to know where is it used these days - what amps or radios use it.

    Wondering if it would bring more value to sell it complete with all 12 tubes, or part it out.

    Thank you for your advice.

    (Please note this is NOT a "thinly veiled" sales listing. I will follow the rules and put up photos with my call when time to sell).

    Used sweep tubes from a CB amp aren't worth much at all.

    There is a place in McKinney Tx right down the road from you that might be interested in buying it. Check your local CL for directions.

    I would have taken those tubes off your hands in a hurry about 40 years ago. ;)

    $5.29 each brand new with a lifetime warranty from Radio Shack in 1970.:)

    Unfortunately, my DeLorean "Back To The Future" time machine died a few years ago, or I would be back in 1970 buying up an inventory of Radio Shack tubes. Forget gold, Vacuum Tubes was the investment for the 70s.

    Certain tubes, sure. The majority cost less now than back in the day.

    I think that warranty expired....

    I have some Radio Shack tubes that died and I'm patiently waiting in the vacant lot where Radio Shack used to be so I can trade them in for new ones, under their warranty.

    I hope they start building soon.
