Dak mark x am / ssb cb radio telephone - very nice


Here is a very nice example of one of the best CB Radios ever made...The Dak Mark X. This radio is a must for any serious CB radio operator. Studio quality plate-modulated audio will have will have your friends and other CBers drooling with envy every time this Dak goes 'On Air.'
Loaded with all the most desirable features: The clarifier has been unlocked, the power supply has been beefed up, and the modulation circuitry has been reworked using expensive matched pairs of audio amplification transistors....producing louder audio and lots of forward swing. With fresh lightbulbs, tubes and a precision alignment this Dak puts out legal limit + when tested into a Bird 43 wattmeter & Bird Termaline dummy load. The cosmetics are very good for a rig of this age, however the front panel silk-screen lettering is showing some wear. I rate this Dak a solid 7+ on looks and a 10+ for performance.
Dak base-stations are well known for their very rugged electrical-mechanical construction. No expense was spared when designing these professional rigs. They feature silky smooth controls with large machined aluminum knobs and expensive double insulated switches that are strategically arranged amongst the oversized channel display and large easy to read meters. These are big radios in every way... sound, performance and size.
Lets see what makes these workhorses tick: Remove the 26 chromed cabinet screws, pop the hood and it's easy to see why these radios sold for well over $500 back in the 70's. Start with the oversized power supply transformer that powers a full blown 40 watt Push-Pull AM modulator amp. Not some cheesy little car stereo chip like most radios use. Now feed this powerful distortion-free audio to the plate of the final output tube and watch your intensely LOUD AUDIO bang the huge modulation meter around as it sends receiver needles swinging throughout CB land. Of coarse with all this talk power a good radio manufacture employs built in Common-Mode Chokes preventing stray RF from traveling down the power cord and a true Low-Pass Filter just prior to the antenna out. The receiver is exceptionally tight and the transmitter spectrally pure, making these radios ideal for operation in government radio rooms, such as the Coast Guard, Highway Patrol and other Law Enforcement agencies.
With over 1000 hours bench time logged on Dak radios I have gained a vast knowledge of both grading and repairing these enormous CBs. They are the 'Rolls Royce' of CB radios. One of the photos below is part of my Dak collection. At one time I owned 12 of these highly collectable transceivers. Only the radio featured in the close-up photos is for sale.
I have poured numerous hours into the restoration of this and all my other Daks, then more time with a complete alignment. There is also the cost of the tubes, bulbs and component upgrades. Needless to say, even when these rigs sell for $500 or more, I'm barely breaking even. I do it for the love of these great radios and to gather as much info possible. The MH Scott Company made many production modifications throughout the short run of the Dak X. I have made notation of these, most quirks and come up with several design improvements. All this will be soon available in my new manual.... Care and Feeding of your Dak'.
The following restoration work has been performed:
Cleaning of all controls with a light protective lube.
All factory original matching hardware (rack mnt & cabinet screws). These items are often lost.
The interior electronics have received a high pressure cleaning just prior to the alignment.
Complete alignment / test. Then I give the radio what engineers call the 'Burn-In Test' running it hard in all modes for more than a week before granting it my seal of approval.
