Bakelite
I am not sure how to fix this, Bakelite is a thermoseting plastic, which means it won't melt! BUT it is Very Brittle. It is also Opaque.

The picture at http://en.wikipedia.org/wiki/Image:Radio_Diora_Pionier_U2_1.jpg actually looks more like bakelite than wood, but I can't tell for sure.

Thermoplastic did sometimes melt. Many of the thermoplastics are semitransparent. cmacd 15:03, 24 January 2007 (UTC)

Actually it looks like, marbled polypropylene, regular plastic. Bakelite is real thick, about 3/16" thick usually or more, quite heavy and solid brown or black. The best way to repair is to use epoxy, like "JB Weld"tm 8 hour dry (Any Hardware Store) stir mixed 50/50.  Because of dry fast weakness, do not try to use "JB Kwik"tm 1hr dry.  "Dremel"tm out a "V" groove, on both sides of a crack, or masking tape the unfilled side of a hole, then fill. Do one side at a time.  Best to overfill then sand off flat.  Unless you are practice, at mixing colors into epoxy, you must later spray paint entire cabinet.  There are clear epoxy’s for marine that you can mix to obtain special colors and marbling.  This method works great for all plastics including Bakelite.  Bakelite is extremely tough, held together with internal cloth fibers mixed in, not brittle at all.  "JB Weld"tm has iron fiber hence very tough and paints well.  The coefficient of expansion are quite similar in this Epoxy and Bakelite. 98.77.156.89 (talk) 05:03, 12 August 2010 (UTC)

To Do

 * Section on moving iron speakers split off to its own article
 * References would be good
 * Replace 1958 radio pic with typical pre-war homemade rad pic.
 * Perhaps add a few more sylish radio pics dotted around the article
 * Add (links to) sound recordings of moving iron and inductor dynamic speakers, and perhaps a 20s/30s radio
 * Not sure whether to split warm up times off
 * There are various related wiki articles that need reading and interacting with

Recordings
Would be nice to add a recording of some early speakers/sets. Question is what could be played in such a recording without there being a copyright problem?

What is PAT? and HT?
The acronyms PAT and HT appear in this article, but if you click on either of them, there are quite a few things each might mean, and I was not able to figure out which were correct. Note: I am American, and I suspect PAT might be a regional TLA the UK, since words like aerial are also used in the article. Maybe someone who knows what these abbreviations mean can expand them for a wider audience. Thanks! CosineKitty (talk) 02:01, 11 June 2008 (UTC)
 * Five years later, the article is still an uncomfortable mixture of British and American English and terminology. PAT is Portable Appliance Test, a UK electrical safety test. HT is BE for B+. --Ef80 (talk) 00:40, 25 September 2013 (UTC)


 * I agree, this article is a real mess of foreign English and unexplained acronyms and Britishims. I would fix it and clarify the grammar (which neither Oxford nor Stanford would find acceptable) but usually some twit just comes along and reverts it immediately with no explanation. "Euro-phileism" is a creeping disease on Wikipedia.  — Preceding unsigned comment added by 73.93.154.192 (talk) 20:15, 6 April 2018 (UTC)
