D&A Maverick Repairs

 This is a D&A Maverick RF amp. These are easily tapped for 40-10 meters monoband, later models had band switching. The PA runs pretty much like a Dentron GLA-1000 or the Amp Supply LA-1000. The 6KV6A driver section allows operation with lower powered rigs in the 5-25 watt range. The driver section can be bypassed for use with conventional 100w output rigs. 

This unit had lots of problems, and may have been a parts unit. It was missing the tuned input, missing the driver cathode choke, the PA load control was shorted to ground, was missing the input coupling cap, PA tank was broken loose from the tune cap, had bad caps in the rf sensing circuit, wiring issues, and cooling fan issues. All this was repaired, and she's running like new.
