I've since got in contact with Joe Malone and found out that without the trim pot you can simply bridge the in and out terminals which would usually go to the trim pot. I did think of this but was unsure if I would need a certain amount of resistance in there but for full output gain this is not the...

Hi there, I have searched high and low on this forum and the web and can't find out how to make sure that the output gain on my 1290 micro kit is set to its highest setting? The main problem I can see is that all of the schematics etc show the kit with an 'output push/pull trim pot' (which I don't h...

Looks great Mark, looks like you had fun designing/making that faceplate... Mine looks great in my head right now ... Lets hope it looks as good once it becomes a reality, I'll be sure to post some pics! I can't wait

Hi guys, Just wondering if the 1290 micro has a build thread like some of the other kits do? I've looked and searched everywhere now and can only find the schematic for the stereo 1290 everything kits. I've built my 1290 micro now with a few minor problems which Joe has helped me with (Thanks Joe ;-...

Thanks for the replies! nice info, my needs have evolved yet again... All I need now is 3 to 6 leds to come on when I switch the unit on, so I was thinking to wire this straight over the original on/off led with the new calculated resistance value (so running straight from the 48v supply) and then j...

Thanks again Joe, sorry for the bumps
That sounds great, I may buy the VUPPMGR40 led meter for it, can the led's be changed for blue ones? bearing in mind the blue led's need a higher voltage I believe?
Thanks
Brett

Hi Joe, thanks for your reply, I have a very good but now very distant understanding of electronics, so didn't know about the leds not needing the buffer, so that is a real bonus for me! However I've since modified my needs, I am going to need the meter to be switchable between input and output and ...

Hi, I just brought a 1290 mono kit from JLMaudio and can't wait for it to arrive! (May take some time as I'm in London!) Anyway I have really big ideas for the presentation of this unit and really want to incorporate an all led variable vu meter as a backlight, possibly across the input or the outpu...
