Can someone tell me the min safe voltage on the input and second stage coupling caps. I have the schematic and could use the assembly instructions and parts list if someone is willing. I purchased a preowned unit. Can I assume that all resistors are 1/8th watt unless specified?? Thanks, Tweaker
There is no more than 70 to 80 volts across the coupling caps. One can use a 100+ v cap. I am being told that there is no DC coming into the circuit from equiptment and that the first coupling caps, C1 and C2 can be done away with. I am also being told by some traind in electronic with lots of audio experiance that C5 and C6 can go down to .047 MF. I like facts. Tweaker
There is no way that the min voltage is 630v. Looks like B+ is no more than 185v and no voltage on the circuit is more than 350v. I am being tolded that film caps are extreamly conservativaly rated, as mucs as 100%, meaning they can take 2 times the voltage rated . Now don't do this, and I have not checked this out but it seems to me that 630 v is unecessary. Tweaker
