Sometime last year I modified my Heathkit W3-AM based on Talbot Wright's 1961 article at Electronics World. I love this amp...powerful, clean, detailed although I find the bass a tad leaner than the original.

I have a photocopy of that article and I couldn't figure out 2 values. If anyone has the original Electronics World article (page 105), would like to know R5 and C3 of the feedback circuit. I installed a 10k and 75uuf in parallel, but recommended values could be different.

By the way, anyone using the W3-AM?
