|| 6BQ5 USA makes such as GE, Sylvania, etc. (Not RCA)
New (NOS) These
are all very high quality tubes and will sound better and outlast the
currently produced stuff from Russia, etc.
USA Makes As Above But USED TESTED GOOD
|| RCA 1950's thru 1970's New (NOS) These
have gray plates and usually have a black graphite type coating on the
inside of the glass which is to minimize electrical radiation.
This coating gives them the appearance of being used but make no
mistake, it is normal and they are GREAT TUBES. These are thought
to be the best of the 6BQ5/EL84 produced in the USA.
||CMI Brand (OEM) made by RCA 1969 date code New (NOS) These nice tubes were made by
RCA for CMI. They are all of the same date code They were "bulk
packed" so they come in white boxes.
|| Westinghouse 6BQ5 USA
Nicely made 6BQ5's made in the Westinghouse factory during the
1960's. Only 5 or 6 available currently.
|| CBS/Hytron 6BQ5 USA New (NOS) Good Ol' American made
tube Only 1 pair in stock currently
|| Tung Sol 6BQ5 USA
(NOS) RARE RARE RARE. These look a lot like Amperex
EL84's inside. I only have a few of these at any given time.
|| 7189 Sylvania, etc. USA
New (NOS) This
tube is slightly more rugged than the standard 6BQ5. They are
very good quality tubes and getting HARD TO FIND!
|| 7189 RCA USA
New (NOS) The
"ultimate" American EL84....RCA 7189. Get them while you still
differ somewhat in pinout from 7189/6BQ5, so if your amp calls for
7189A you need to use these. GE is the only US mfr. to make 7189A
are an excellent sub for 6BQ5's. Save $$
8BQ5's made by Sylvania, GE, etc.
