If not too late, I need a MK-U47 PCB (without R6/R7 and without the pattern switch) for rainton's case. Zayance, are you going to have any MK-U47 PCBs for sale in this latest order? Unfortunately, the holes on the MK47 PCB I have do not line up with rainton's case...
Does anyone have a building guide for the MK-U47 PSU?
I have followed the scematics for ioaudio's MK-U47 mic and really wonder about the connection to the mic cable in the psu and which pin goes to what.
Well, i received emails very fast asking for them.
While i was at work, i was counting the interests just for having a clue of quantity.
Yes pretty fast, and wasn't much expecting that, reorder soon anyway so no worries.
Zayance, Im interested in a pair of the Federal comp boards. Would you recommend getting your stepped attenuators with this project for input/output? ( I would assume 4 of them for input/output... or should i steer towards using the Log pots as specified in the BOM?
The input pot is a stereo pot, so with a lorlin that would make only 6 steps. The output pot is just a 10 dB attenuator. Using stepped pots here wouldn't make sense. For ratio and threshold a stepped pot would be great. I hope that helps.
So using multi-gang greyhills or something on the input? I'm just thinking about recall-ability. I would actually want to do all of the controls stepped if possible except the attenuator (now that i think of it, being a tube circuit, the probability of the two sides being dead on even is probably not all that good unless every component is matched, and even then, there still could be discrepancy)
