DenTron Radio support FAQ

Common questions about manuals, registration, and support for this brand.

  • Where can I find replacement parts for my DenTron amplifier?

    Since DenTron Radio Co. is no longer in business, parts such as tubes and capacitors can typically be found through vintage electronics vendors, specialty amateur radio shops, or secondhand marketplaces like eBay.

  • Can I use a DenTron amplifier with a modern solid-state transceiver?

    Yes, modern transceivers can be used. However, you must ensure your transceiver's output does not exceed the amplifier's maximum drive input (e.g., 125W for the GLA-1000B) and use proper T/R relay interfacing to avoid damage.

  • What kind of tubes are used in the DenTron GLA-1000B amplifier?

    The DenTron GLA-1000B uses four 6LQ6 (also known as D-50A) sweep tubes in its output stage to provide approximately 500W CW output.

  • Is it safe to open my DenTron tube amplifier for maintenance?

    Tube amplifiers contain life-threatening high voltages. Always strictly disconnect the unit from power and wait at least 30 minutes for the electrolytic capacitors to fully discharge through the bleeder resistors before removing the cover or performing maintenance.
