trumpetsplus, I understand now what you mean. When you originally said thinly plated, I didn't think you meant too thinly plated, because nickel plating on valves is always quite thin. I guess that in this case, the OP should hope that the valves are monel. Generally, though, you said that Monel is worse- this is an interesting point. It would make sense to me, as I've found that the best valves are not monel, but I'm wondering Monette will now do? If they are selling horns at that price, you'd think they'd be making stainless steel pistons by now. Why are they still stuck on monel? Or am I making a mistake here, and Monette no longer uses monel?
