I have a number of books I use, but would be intrested to hear other peoples ideas on there refference tomes.

Mine are in no particular order ...

HiFi year books '72 & '74

HiFi choice the little A5[?] ones with catchytitles like Turntables and Tonearms.

Newnes Audio and HiFi Engineers pocket book.

To name a few. I always keep my eyes open for secondhand books but its useful to know a few other titles to keep looking for.
