MFNAKD... C3 SLO-100 minus 50

Big one is Odin
120 ish lbs (cant lift him and get on the scale with me anymore .....him plus me .........MAXES the scale and over)
Athena is less than a year old and 90 lbs
Anatolian Shepherds (AKA Kangal Dogs) google them ......AMAZING animals

we have a dozen or so others running around as well......but smaller .....lol
 
Finished this build a couple days ago. Fired it up yesterday, but there is an issue in its operation that I haven't been able to figure out yet. This amp is a two channel amp: The Normal and the Overdrive channel. On the Normal channel there are two modes: Clean and Crunch modes. On the Clean setting is where the amp is acting goofy. I've just got through sending an email to C3 Amps describing the problem in more detail, and also sent a voltage chart of the amp in general, which fortunately are in spec. And also sent a voltage chart of the amp's switching supply... which might be the culprit here.

The Norma channel's Crunch mode is f'n awesome... The Overdrive channel is even awesomer! Stay tuned...

Can you get a move on and finish man:wink:, Im dying to hear how it chugs and if low end gives me seizure:shock::thanx:
 
OK, maybe, just maybe there has been a little progress in trying o figure out WTF wrong is happening. Still waiting to hear back from Mr Rob Reeder from the latest barrage of info I sent him. The problem seems to be somewhere in the switching circuit. There are 4 to 5 resistors involved in supplying proper voltages to the four vactrols or LDR's that do the switching. One of the resistors that I installed was a 47.5K (47,500 ohms) where the proper value is suppose to be 47.5 ohms. I temporarily corrected that to a 47 ohm resistance, but the amp is still not behaving properly. I sort of bypassed one of the LDR's that I've been suspicious about, and sure enough the problem seems to have gone away. Still not sure if that LDR is bad, but I'm thinking it is... :unsure:. Getting closer... :flash:

While frustrating, these situations are the best learning experiences. Nice layout BTW - very neat work!
