Re: Ladybird Book Making a Transistor radio
There was also Radio Construction for Amateurs again by RH Warring https://worldradiohistory.com/BOOKSH...rs-Warring.pdf

by which time I was well away to boarding-school and playing around with the CCF's WS31 WS88 and C12 transceivers on HF and VHF!

Re: Ladybird Book Making a Transistor radio
Ah, I see. It must be an earlier book.
Incidentally, quite a few of the radios in tha RH Warring book use germanium transistors, though some silicon types are also used. Regards, Symon |

Re: Ladybird Book Making a Transistor radio
I wonder if it could have been "Making Transistor Radios" by R.H. Warring? This was the book that got me started when I borrowed it from the mobile library that came to the school. That one had a green cover with yellow writing but I subsequently was given my own copy for my birthday with orange writing on the cover. You can find the first printing at https://worldradiohistory.com/BOOKSH...de-Warring.pdf

I'm tempted to try re-creating some of the designs; I have foind memories of playing around with a Reflexed receiver built from that book, which worked quite well using an OC44 as the RF transistor. I remember though burning my fingers on an OC81 used as a single-ended Class-A audio output transistor when its simplistic bias-network let it go into thermal-runaway. ah, happy memories!
