    D & A Manufacturing Maverick 250 Linear Amplifier

    $100.00 OBO ( Local PU ONLY )

    This is a used Vintage Maverick 250 Linear Amplifier that does power on and all tubes light up.

    Both transformers look fairly NEW!

    Moving soon & do not have time or funds to look into & repair at this time!
    Will NOT engage when radio gets keyed.
    May Just Need a set of Tubes, Don't Know!

    No further testing has been done. This is being sold as is. For Parts, Not Working !

    is this a cb amp or is it broad banded enough to get on 10 meters? what tubes does it use? I don't see a band switch is the reason I asked.

    It says: "CONFIDENTIAL" on the face plate. Is this amp from a pirate or a clandestine operation? WWII perhaps?

    Please explain.

    Thank you.

    I'm thinking that this will work on 10 and 11 meters with no problem. Attached is the schematic.

    When new they would work on both 10 and 11 meters. Most 11 meter operators moved the tap on the tank coil to increase power on 11 meters. If it has good tubes check and if you would like more power on 10 meters relocate the tap on the tank coil for more output.
