There is absolutely no reason to match any USA made versions. One source is 
someone with old car radios, the 6V6 was used extensively in single and PP 
stages from the 40's to mid 50's. The PP Buick Delcos sounded better than 
any ham or SWL receiver for some reason and that includes my NC-240D's.
