I searched, and came up empty. Does anyone have a step by step Process for swapping in the IRF520 into a 29LTD Classic. Pictures would be appreciated. I found the paragraph explanation from dtbradio but it leaves a lot to be desired as far as clarity. I ordered a 5 pack of the Mosfets and have a pretty wide assortment of resistors, caps and diodes from a few years of electronic tinkering and the clearance sales at radio shack recently. I would just like a little more explanation than what is supplied from the dtbradio blurb that is often reposted. It appears the eBay sellers have an instruction guide they supply when you buy the kit from them, if anyone had a copy of this it would help a lot.
