Does your transmitter have original Browning branded tubes inside? Browning used several hi-quality glass vendors. Some lucky folks may be surprised to learn their transmitter contains some very exotic audio-glass now valued at well-over $200. Five pages have been dedicated to the extremely important tube selection and replacement, outlining proper tubes brands and the performance they will deliver.

Not all tubes are suitable for use in Browning's.  You can get a 12AX7 tube for $2, $20 or $200 dollars, which one is right for a Browning?  Does your squelch seem funny?  There's only one manufacture's tube you want plugged into your receiver's V9 socket. Anything less and you'll have a goofy squelch.   I have painstakenly tested both the exotic, and lesser glass throughout the various stages of Browning MK-III and offer many suggestions for those that want louder, distortion-free audio. 

Did you know there were 3-different versions of the Mark III? Browning Labs made several production changes throughout the 1971-1976 run of the Mark III. Which version was best? As an owner of numerous Browning Eagles, I've formed a strong opinion and it's all right here.

The 'Buyer Beware' section arms potential buyers the info needed to evaluate Mark III's like a seasoned-pro.  With over three decades of electronics engineering and tech repair experience, I've put together several very important points and purchasing questions to ask when considering any used piece of electronics. The answers yield very important info about the condition and the value of the electronics being considered for purchase.

They did a great job on the ruggedly built Mark III's as the numerous consumer reports and magazine reviews will tell you. However, after 40-years of component aging, dust and other contaminants, these radios will benefit greatly from the step-by-step procedures outlined in this manual.
