[Market price for black KLF30s and oak KLF20s]

How much would a pair of KLF 30 (black) and a pair of KLF 20 (oak) in Excellent condition go for in New York area?

Currently I do not see any on eBay so I'm not sure what people are asking?

Hi I'm interested in your KLF-C7s and KLF30s.

I would be looking for two of each. Do you have 2 unopened C7s? What condition are you KLF30s? Do you have pictures?

I live in New York City how would you ship them?

[KLF 20 - X-over Upgrade]

I came across this at the audioreview.com site under KLF-20:

**** "A quick look at it shows that the parts are ALL VERY LOW GRADE ! Which means that there is a lot of room for improvement.

So if you can solder, here is a quick-and-dirty recipe (please, if you don't know, don't take the risk, and don't blame me):

- replace the yellow caps in the middle (2 are 2.86 uF 200V 15% in series, 1 is 1.25 uF 250V 15%) with high grade polyprop like Audyn Caps, Hovland Musicaps or Auricaps.

- replace the long ferrite self (1.75 mH) with a very large self of the same value from Jantzen audio for ex. (1.7 mH www.jantzen.com), and the smaller self of 0.175mH with a larger one of a close value (0.17 mH).

Replace the resistors from T+ (tweeter) by two Philips PR 02 or PR 03 of the same value.

Replace the caps in the black box by Elna Silmic II (same or smaller tolerance) for example. " ******

Does a cross-over upgrade exist and would it make much of a difference?
