At long last I have managed to find time to make the above circuit. HOWEVER the circuit was first published in October 1977! Unfortunately I do not have any following issues of the magazine from that year. My question simply put..... did anyone make the aforementioned circuit and if so were all the component values correct or were any revised at a later stage. I would really appreciate any advice/help that anyone has to offer.
Yours sincerely, (and in anticipation)
