After this weekend, I have got about 60 hours of time on my recapped LM 518ia. Things are progressing nicely, and the sound is really opening up. I agree with what a couple of the previous posters said. Recapping just for the sake of recapping might lead you down a wrong path. I started this process with a plan, and some knowledge of what a recapped 219 and 518 sounded like. I was able to do a direct comparison between my stock 518 and a recapped 518 and 219 using V-Cap CuTF's. I liked what I heard from both amps, and went for it with the help of Pat Hickman from Classic Tube Audio. Early listening indication are all positive so far. I've never had any transformer hum from my 518ia. The stock rectifier got replaced on the first day, and she is plugged into my PS Audio P5.
