D+A Raider all dressed up, + showing the baby D+A's: Hawk and Hornet + a glitch at the end.

D+A was an amplifier company that made mostly 'CB' amps from the 60-70's. D+A amps where actually designed and made by 2 Hams back in the day. The Hams were named Dulaney and Allen, hence the D+A name. They made a bunch of sweep tube amplifiers from the 1 Hawk, 2 tube Hornet, to the 10 and 12 tube Phantoms, to the 16 tube Warrior. The Raider is a small 4 tuber using 4 baldies, all outputs, no driver. Some used a tube keying tube while later models went with a transistor keyer.
All D+A's including this one are grounded grid. No Turbocharging and hence no audio monsters. Some had preamps called BTL for BiLateral back in the day, but the preamps built into amps was junk. Brought in more noise than signal. Want a good CB preamp, get a CPI or Pride. As with all CB amps, this was made for 4 watts drive or less. So many people hit these with a lot more watts and kill them quick. They will do more watts, but not for long.
I've had this one a while and had been looking for some good 6kv6 tubes to put in it. 6kv6 tubes are the best of the baldies. 6jg6, 6jt6 and 6jr6 are other baldies that are interchangeable, but the 6kv6's are by far the best of the bunch. I guess a lot of people figured that out because the price of the 6kv6's has skyrocketed. Even the odd filament ones like 17kv6 and 22kv6 is hitting the roof. Since I had 4 NOS 22kv6 tube lying around, I decided to do something I don't normally like to do. I put in the 22kv6's and ran them in series added a dropping resistor, and ran them straight off the AC mains! Yeah, it works, but it is not the safe way to do that. I'll give myself a pass on this one though LOL.
The Raider is just a one stage grounded grid amp. It runs on a pretty low 800v unkeyed and 600v keyed and is basically a 100 watt amplifier. It dead keys 50, swings about 75 RMS and 125 peak with the mud duck radio going into it and on a dummy load, no false watts. This one is in good shape internally but only fair externally or physically. I give this one a 6 1/2 on a 1-10.
The Hornet is like 1/2 of a Raider, uses 2 of the same 6jg6 baldie tubes. Since the Raider is a 100 watt amp and the Hornet is 1/2 the Raider, then of course the Hornet does 50 watts.
Last and least, is the Hawk. It uses 2 6gk6 tubes which are basically 6bq5 tubes with a different pinout. Baldie tubes are rated at 17 watts, 6gk6's at 13 watts, and 6lq6 tubes 30 watts.
At the end of this vid, you can hear the Raider making a glitch. It will take a sharp eye and a sharp ear to put together what happened and why. I already addressed and fixed the issue and a kudo and attaboy to whoever figures out what happened.
