Closest to pass labs int 250 or x250.8
My Coda CSiB is the V3 version. Thanks for your reply, Mark, I have a V3 also, just wondering is the V1 will run much hotter?

@meambler  Which version of Coda CSiB  you have? V1, 2 or 3?

4.85V 1/2C Cell Array BatteryDoes this make sense to anyone? @tonyaudio   1/2C is the battery size (Dia.26x24mm L), 4 batteries in series = 4.8V (1.2Vx4). Without seeing the actual battery compartment, just a wide guess. http://www.batteriesinafl... 
Preamp Output Capacitor: Mundorf Supreme vs. Supreme Silver Oil
If you read a lot of capacitor discussions, you can see some other people finding that the bass response of the s/g/o decreases over the first 300 hours (e.g. https://forum.audiogon.com/discussions/mundorf-silver-gold-in-oil-supreme-caps-any-go...

they had no bass (actually, they lost bass as they broke in). The capacitor lost it capacitance after broke in ?  
Amplifier power supply voltage - moving between regions
For safety reason, does it require double pole switch if both legs are HOT?

Converting stereo single ended to balanced mono?
@unsound Please take a look the Marchand bass equalizer https://www.marchandelec.com/wm8-bass-equalizer.html Contact them and see if they can provide something you need. 
Looking for a sub to put in my amps loop function
6 dB/oct low pass is too slow for a sub. You will have it running up into the mid range. IMHO 12 dB/oct is the slowest I would use. For example, if the loop input impedance is 10kohm and a 0.2uF capacitor inserted to the loop to create a 6dB/oct r...

@audiokinesis and contuzzi, Yes, I agree that the subwoofer should not connect directly to the loop which is before the volume control. 
Looking for a sub to put in my amps loop function
@contuzzi, Please read the Vandersteen 2WQ manual: https://vandersteen.com/media/files/Manuals/2wqmanual.pdf You can insert the capacitor to the loop and connect a subwoofer to preout or speaker output as long as the subwoofer has a contour opp... 
Looking for a sub to put in my amps loop function
@audiokinesis For example, Vandersteen 2WQ insert a capacitor to the loop to create a low frequency 6dB/octave roll off, and the subwoofer connected to the speaker output and the contour is opposite of the low frequency 6dB/octave roll off induced...
