[QUOTE="Ampdog, post: 63348, member: 144"] Hennie, I bought Elma switches from 'iS ELECTRONICS', 11 Stott Street, Wemmer, Jo-burg. Their landline no is: (011) 493 3630. I do not find their e-mail address right now - perhaps on the internet. But this was 5 years ago! At that time the price was R285 for a twin wafer mbb with a 25-position index. Might be double by now! The contact person was then a Mr Pothiah. They also stock other Elma components. You will no doubt be aware that one can also buy the attenuator with resistors mounted, but the price for that was > double. It takes some time to mount one's own resistors, but then one can incorporate any 'law' one wants. I have worked out loudness control values, which give quite accurate contours over 60dB except right at the bottom, with four additional RCs involved. (The impedance is about 110K, but one could of course scale to any desired value.) [/QUOTE]
