Re: JLM 60Watt Power AMP Kit
Hi Joe,
thanks! I will move the trafo to the left side and both ampcards to the right. And wire the trafo correctly...thanks for explaining why wiring it like this: phase. if i know why, i can remember it. looking forward to the diagram.

Re: JLM 60Watt Power AMP Kit
Hi there, i've finally managed to build a new stereo amp with the amp kits. it has 3 stereo-cinch inputs, selectable via switch. the volume-poti is an alps 10k stereo poti. Attached you'll find a picture of the build. So far it tested flawlessly and i have sound. I have two problems: The output is r...

Re: 8PAKAMP KIT BUILD THREAD
i've posted some pics on facebook and have linked you on a picture, feel free to add the pics to the jlm-site. just two last questions :wink: i have installed a 2A slowblow fuse. i think that's too low, because it occasionally blows up during start-up. what fuse-value would you recommend for a 300va...

Re: 8PAKAMP KIT BUILD THREAD
could it be, that the + and - speaker-connections are reversed in your drawing?

Re: 8PAKAMP KIT BUILD THREAD
wooops, where is it shorting? with no schematic at hand, i guessed that input-pads 2 and 3 are linked to the trimpot-pads 1 and 2&3, as i can bridge the amps on the trimpod-pads. i'm fine by having different volume-pot-settings between the amp-pairs to have the speakers play at the same level. but o...

Re: 8PAKAMP KIT BUILD THREAD
thx joe! Basically mains ground to chassis bolt with both 0v wires from power transformer and 0v wire from here to one or two of the center large pad holes between the 2 large caps in the middle of the PCB. so both 18v secondaries to the rectifier? then my post above was wrong: the 300v 2x18v-transf...

Re: 8PAKAMP KIT BUILD THREAD
will do so, thx! is this the right way to bridge the amps? this would also help me to understand the insert-point of the volume/trim-pot. am i right to think, the yellow labeled pads are connected? so my grounding of the whole input-section would be: from the two light-blue, in the middle-of-the-pcb...

Re: 8PAKAMP KIT BUILD THREAD
thx joe! Yes as long as the outputs have no dc on them it will switch fine. If outputs are floating with no 0v reference then adding 10k resistors to 0v would fix this. But just try switch with nothing first. are you here talking about connecting signal-ground to chassis-ground with a 10k resistor? ...

Re: 8PAKAMP KIT BUILD THREAD
hi there, i've just ordered an 8pakamp-kit. i would like the amps to run 3 pairs of speakers. there's only going to be one stereo-input. i would like to select, which output is active (switching through speakers while mixing music) . so my questions: can i easily add an "output/amp-selector" by wiri...
