I have the third edition, came out during the 60's, and while it deals with a lot of tube circuits, television never changed until recently with the DTV mess. This book however, is NTSC/US specific. I understand that the basics of operation can be applied to PAL signals and maybe even SECAM. But this book is a great resource on every part of a TV, from the carrier signal to the tuner, oscillator, amplification, gain control and FM sound. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
