Hello all! First off thanks to groupdiy for such a wonderful and informative site, thanks to Mnats for the beautiful 1108 boards and power supply pcb.
I'm building two channels of the 1108 and have a few questions, I'm new to building things of this scale so bare with me. (I'm used to building pedals).
My build consists of: i eliminated the Vactrols and have wired up 1m pots. Input transformer is Cinemag CMMI-7C and output transformer is Hairball Audio's 5002. (Thanks for the great site Hairball and transformers!)
now, my questions are:
1. According to the schematic on Mnats page there are two connections near R20, labeled "E" and "5". I've seen other members have thrown a resistor in the spot. What's the purpose of the connections, or what size resistor should I use? (I couldn't make out the color bands from any photos.)
2. When wiring the output transformer, the yellow and orange wire should be cut and taped off as they are not needed? That's what I gather from the photos and schematic (again, I'm new to this so my "gathering" is probably not correct!)
3. When wiring the input tranny, is it advisable to skip the s3 (impedance) if I know I'm not going to be running ribbons? I can just cut secure the cable and wrap it with tape if I change my mind. And should I go hi or low in regards to the "set it and forgot" impedance?
Sorry for so many questions, i will keep searching and reading in an attempt to figure it out on my own, I just wanted to double check before I wire it up fully and test it, or break something.
Thanks again for any and all help.
