Just bought a KB100. Looks like the serial number plate indicates this was circa 1988. It has no XLR input on channel 1 
Well, that's not the end of the world since it's pretty easy to just use an XLR to 1/4" cable. There seems to be a number of variants on this amp but the Peavey site only archived one manual. Specs are pretty sketchy. I did notice that this model has an indicator light (LED? were they even invented back then 
) for "Compression". I'm assuming that this lights up when the compression circuit is active. The DDT compression as I understand it (probably don't) kicks in to prevent clipping. So, if it lights you're overdriving the input/channel gain. Seems like a useful feature. Don't know why they'd remove it from newer models. The difference between the KB and the KB/A also seem mysterious. As far as I can tell there is an input boost/gain button on the KB/A but the KB (which years hard to tell) had better specs with regard to wattage at equivalent % THD?
Manual says foot switch operates (yes/no) the reverb. When we test drove it (my son is the musician, I'm the gear schlep) it seemed like the reverb wasn't working (i.e. no effect). Do you need the foot switch to "close" the circuit and activate the reverb?
For my next thread, I also recently aquired a 1991 vintage TKO-80. Man did they make a bunch of way different amps with that model number. Some have 12" speakers and some have 15". I think I'm lucky here in that mine has the 15" Black Widow. Since the KB100 doesn't say anything (and it's not mentioned in the owners manual) I'm assuming it's a Sheffield?
