Talk:Pentagrid converter

message: I have extensively rewritten this article.  I have included the Hexode, and Octode into the story as there is not really enought to justify a separate article.  I have endeavoured to keep the content that some contributors felt was valuable enough to put in the article.  Sadly some, I couldn't really work in without disturbing the flow - If you can work it back in without upsetting the flow, then feel free.
I particular, I have removed the lists of valve (tube) types that were used in the All American Five.  These are better documented in that article, and it seemed rather pointless to duplicate the information.
There is also a fetish for adding links to valve or tube numbers.  There really is no point unless you supply the linked to article as well, otherwise there remains rafts of broken links.
I know that Cmacd123 is awaiting this rewrite.  I should be interested to hear your observations.  I took the liberty of removing your discussion points as they do not relate to the new article (and some had bee addressed anyway).

message: I don't want to start an edit war.  What reference do you have that the Pentagrid converter was in any way invented outside north america?  The Mullard design you quote was NOT a pentagrid.
BTW I am NOT american

thread_title: Mullard not pentagrid

message: I can understand that the idea is that perhaps a full article on Superhetrodine conversion is what one was tring to do, but A pentagrid converter IS a tube with 5 GRIDS used for superhertodine conversion.
It was CLARLY Ivented by a dude working for RCA in the States.  (I wish it was some Canadian)  I had the actuall patent number there,
:I'm not saying RCA didn't invent it.  What it appears, is that it was independently invented here as well, and patented.  As I said, the UK version was implemented differently.  You are right in one respect: I inadvertantly dropped the patent number - I shall put it back.  Rember that Alexander G Bell is credited with invention of the telephone, but someone completely independantly invented it and turned up at the patent office just a few hours after Bell (and firmly believd that Bell stole it).  It happens.  It happens a lot!86.133.15.213 17:53, 5 July 2006 (UTC)
replies: text: There really isn't enough to justify articles in their own right.  I think a better solution would be to make the pentagrid article more general on frequency changers (which was my intent (except I don't know how to change the title and adjust all the links, so a bit of help here would be useful)).86.133.15.213 17:53, 5 July 2006 (UTC)
thread_title:  PENTA is Latin for 5  

message: Listed at the end under Valve Manuals are
    * General Electric Essential Characteristics, 1970
    * Sylvania Technical Manual, 1958
Niether is a valve manual any longer.  — Preceding unsigned comment added by 99.2.69.235 (talk) 22:22, 20 March 2012 (UTC)
replies: text: You mean that the contents of those publications has mysteriously changed while sitting on the book shelf?  I can't speak for the first, but the second still has details of many valves (vacuum tubes) and I can atest that they have not mysteriously fallen out of the manual.

thread_title:  Links Gone Bad 

message: Wow, that was a fast decision. Actually, I wonder. 86.145.140.242 is certainly right about the inconsistency; I understand the term "Pentagrid" is defined as a coincidence mixer with an electron-coupled oscillator; that'd throw T/H mixers out.
Under the top lemma Frequency mixer we have:
*Ring modulation
*Gilbert cell
*Product detector
*Pentagrid converter incl. T/H
*Beam deflection tube
Looks like we still have nothing about nonlinear VHF/UHF mixers, neither triode nor transistor. Where would that go? I too doubt T/H, Beam deflection and VHF/UHF nonlinear lemmas will ever reach Start-Class.--Mkratz (talk) 20:49, 26 June 2013 (UTC)
