Re: Performance question
I've never heard of it, but it sounds like a variation of the old 10k resistor mod. If that is what it is, don't waste your money (save it for a decent multi-position chip). Just search on 10k mod or similar and do that mod for 50 cents (or whatever a 10k resistor costs these days). Cheers!
