I've got a scott schwartz 3208 analog delay build, which I think I may have accidently fried (connected it with the wrong polarity). what's the best way to determine if a BBD has been damaged ? try testing it on an LCR meter ? what should the capacitance of a cool audio V3205 chip be ? 0.4096uf ? , 4.096uf ? some other multiple of 4096 ? I don't have any control chips to compare with.
any help would really be appreciated.
Use an audio probe. If you've got signal on pin 7 and nothing on pins 3 or 4 then either the BBD or the clock chip has died.
hmm, I wonder if its more likely that I fried the clock chip with reversed polarity, rather than the BBDs themselves...
