I've been internalizing this for a while, but I just want to clear the air. I had quite a bit of work done on a vintage Marshall a few months ago and I can't get one or two things out of my head. The amp came to me biased for KT88s and it had a PPIMV installed. I told the guy remove the PPIMV, bias it for these EL34 tubes which I provided, and check over the entire circuit to make sure it's vintage stock. After receiving the amp back, I opened it and found that at least a few components are still in need of change. The power amp grid bleed resistors look to be the same as they were when the amp was biased for KT88s, 150k value. Stock Marshall value is 220k. The bias ranging resistor wasn't reverted to stock either, it's still the value that was "modified" to fit KT88s. The guy said this didn't "need" to be reverted, but it still bothers me. So there are at least the three components, if not more that I am missing. Do I have reason to be upset? Should I go back and see if he can complete the changes?
