I don't know how many people are getting opamp distorion with the Kingslayer, but I'm trying to think of possible workarounds.
I've only tried the suggested chip since I didn't use a socket. Anyone tried a few different chips?
I was just looking at some data sheets and I'm tempted to go with the TLE2074. Yeah, $4.72 :o
It's got double the supply voltage range and that 35v/us slew rate. I like the dual version quite a bit, just don't pony up the cash all that often.
The only situation I got noticeable op amp distortion in mine was with all diodes lifted and the gain cranked. Mine went all the way up to oscillating in that situation.
I think I'd try Brian's advice of reducing the 1M feedback resistor before resorting to a $5 chip.
I'm getting it - to a degree - whenever I have the soft clippers lifted and the gain cranked. I'm sure I'm noticing more because I'm experimenting with a clean blend, so I have the gain higher than I normally would.
Thanks for the tip. I hadn't seen that suggestion.
