>> (rip), CQ and other mags.
>>
>> The 4cx1000 first starts to appear in the late 50's

>> which I've seen, have but not "yet" posted on sonic.
>> >From my previous requests about the Loudenboomer

>> the most popular tube for the Loudenboomer?
>>
>> A few people have replied with many of the various
>> 4cx1000 magazine article references. Again a big
>> thank you. I'll pass this information along to Ralph
