I just recently purchased a used King 2280 in superb cosmetic condition...it was originally purchased in 1984, so it's been played...a lot. I've had it professionally cleaned and serviced and I love, love, love it's dark tone. But I'm getting annoying, persistent clatter from all four valve guides as they bounce off the side of the valve keyway in the valve housing as I'm playing. There's a fair amount of slop detected when gently twisting the keytops back and forth.
1. Is there anything that can be done to remedy this?
2. My understanding is that the newer 2280s have replaceable nylon valve guides. Is it practical/possible to replace the existing valves with the newer style?
3. Are newer models built better/worse than those circa 1984?
4. The seller has offered to purchase back the horn if I so desire. Should I consider a new 2280?
5. Am I making too big an issue out of this.
Thanks, in advance, for your feedback and suggestions.
Best regards,
Bob Leety
