Hi. I'm a semi retired Design Technology teacher with some limited Electronics teaching under my belt. Had an interest in Hi Fi and technology since the 70's and remain stuck in a 70's 80's funk groove in my music taste. Actually enjoy all types of music but that's where my roots are. I've always kept an eye out for vintage stuff which is how I came across this forum. I have an old Leak Stereo 70 amp which has been in the attic for at least 20 years. I think i bought it from a junk shop..working for £5.00. I used it for several years until it was superseded. My son prompted me to get it out to test a pair of old Pioneer CS-88a speakers he'd rescued from a skip. It turns out one is good, and the other goosed! The Leak also seemed to have developed problems in being laid off. So...what to do? I want to get both amp and speakers working in some form as a lockdown project. I came upon [URL='https://www.audio-forums.com/members/mjp200581.10630/']mjp200581[/URL] 's really informative thread which covers much of the information and guidance I have been looking for. Thank you to all those who have contributed. I hope the Leak is still going strong.
