I have a good-condition, working KA-5700 purchased a few months ago from a Pittsburgh Antique Radio Society friend who had it in his possession for several years. He found it gathing dust on a shelf at the now defunct Mason TV Repair, Route 30, Irwin, Pa. Offset: L 10.0mV R 36.3mV Bias: L 34.0mV R 45.4mV Hopjohn, I thank you for your 3/12/15 thread "KA-5700 Poor Dynamic Range." Wondered if you could field a few questions. Others if you have time and interest, your observations and suggestions please. 1. Would you still go 16V on substitutions for the 10V electrolytic capacitors? I started to select some 25V and thought to stop and ask what you think today. 2. In my due dilligence on pre-amp -- obvious power-handlers looks like you opted for Nichicon PW (C3,4,17) . I was wondering what flavor you selected for emitter-related C11,12,15, 16. Are those KW's? Or what would you select today? Did you use KLs in the power amp C35,36? 3. By the way beautiful-looking work. Super pictures. Other aesthetics aside, how do you pull off such magic-glue-removal results? It appears as if the brown gunk never polluted the PCB. 4. If you were changing out the filter capacitors in the power supply, among the many purchase options what would you choose today? As you know the original manufacturer components are Elna 6800uF42V. Note: might keep the original filter caps if they test good; depending on what you and others think. Please let me know if it would be helpful for me to post schematics. Thanks.
