The article currently says of the early transistor radio:
If memory serves, this is a typo for AM, no? Opus33 03:23, 29 Apr 2004 (UTC)
Transistor radios could not have possibly received the "530-1600 kilohertz AM broadcast band" in 1954, as there was no such thing as a hertz in 1954. It is like saying that Captain Cook landed in the State of Hawaii.
After correcting the detail that the low end was 540, not 530, I see only four basic ways to phrase this accurately.
We can't use a phrasing like "what is now known as the 540-1600 kilohertz broadcast band," because it now extends up to 1700 kHz.
I'm trying the simplest alternative (no explanation). Dpbsmith (talk) 23:34, 13 Apr 2005 (UTC)
Is this really necessary? As a relevant comparison (unlike the hawaii example above), it would be like if the US adopted the SI system, and then it would only be correct to use imperial units for measurements from before today. Your height before today was 6 feet, but after today you measure 182cm. -- Philip Laurence ( talk) 00:28, 18 November 2008 (UTC)
After reading the article I got the impression that the TR-1 used a standard 9V battery. It actually used a special 22-1/2 volt battery (and in the advertisment you can see it mention the battery). Upon rereading the article it isn't clear whether it is talking about the TR-1 or transistor radios in general when discussing the type of battery used. Perhaps this could be made clearer.ЬṛḶ
The History section, while very informative and good contains a number of statements that are quite vague and need to be clarified:
What does 'behind' mean? Produced, marketed?
Do we really need a sentence on something that didn't happen?
What does 'aggressive' actually mean in this context?
While the sound wasn't great, how would we Verify this? Was the sound quality poor for the era?
Hate to be a party pooper, but bring up Bradbury out of the blue doesn't seem very encyclopediac and verges on OR.
What does 'revelation' mean in this context and is talk of a cassette player relevant to the article? Ashmoo 01:56, 18 October 2006 (UTC)
aight,will heyy i really need a summary on this so could you plz email me a summary on the transistor radio,at danieboo@ctvea.net —Preceding unsigned comment added by 72.243.144.100 ( talk) 21:06, 7 May 2008 (UTC)
Under "History" the second sentence clumsily starts "There are nothing to the title of the first industry to produce practical transistor radios..." I can't even figure out how to re-write that - somebody else please try. Paulburnett ( talk) 21:26, 22 September 2009 (UTC)
The section "Transistor radio decline" is very US-centric. While manufacture in one country in the world may have declined and eventually ceased in 1970, there are other countries! Baska436 ( talk) 10:34, 18 October 2010 (UTC)
Wikipedia provides an inflation template to dynamically adjust for inflation. Using this template means that the article will always be up to date. This article had static text inflation. They were already six years old, and quite out of date. So I replaced them in the article with the template. Nick Beeson ( talk) 13:45, 18 March 2012 (UTC)
The article stated 'Transistors are current amplifiers, while tubes are voltage amplifiers' but tubes aren't voltage amplifiers, they are transconductance devices, their output current is proportional to their input voltage. As are bipolar and FET transistors, see here: http://en.wikipedia.org/wiki/Transconductance. Hence I have removed this statement. Jon the id ( talk) 12:41, 18 October 2012 (UTC)
The red lines pointing to transistors are incorrect. The device between the two audio transformers is an electrolytic capacitor and not a transistor.
It is USSR GT108 transistor in top-hat style case - the other output transistor looks like Japanese replacement. BTW, there are two GT309 transistors without red lines: first near the ferrite antenna and second wrapped in white insulation near the blue IF can. -- 89.164.174.168 ( talk) 13:06, 25 September 2020 (UTC)

As a young man, I received a one transistor pocket radio in 1962. It was at a lower price point (one transistor) than previous designs, and more importantly had a low current draw on the 9-volt battery (~5mA vs ~50mA for superhetrodyne designs). An example of the reflex circuit it used is in http://www.techlib.com/electronics/reflex.htm. It used a high Q ferrite loopstick for tuning and a 2SA type germanium transistor as both RF amplifier and audio amplifier, Diode detector, recovered audio voltage acting as an AGC, audio output transformer. As transistor price and power usage declined and bandwidth increased the ball went back to superheterodyne designs. Shjacks45 ( talk) 04:18, 23 June 2018 (UTC)

Hi all - chunks of this article are lifted word for word out of sources, which is plagiarism, and some of those chunks have been cut and pasted wholesale to other wiki articles, which is a no-no. I'm going to trim the detail in this main article, and leave it in the sub articles ie: Regency TR-1, and write this up as a story in our own words, keeping the facts from the citations, of course. Please don't wholesale revert my work, just make it better. cheers Billyshiverstick ( talk) 16:40, 18 October 2020 (UTC)
The English-language article is about portable transistor radios. Elsewhere, like de:Transistorradio, or nl:Transistorradio, it's about transistor radios in general, not limited to portables. Should the wikidata entry be split into two entities or not? Retired electrician ( talk) 21:08, 30 January 2023 (UTC)
