Title: Building a K**ley C4 Comp, help with spanish translation needed
Post by: small fish on January 04, 2015, 07:05:30 PM

Hi,
I found the attached "instruction" to build a Keeley 4K-Comp, based on the tonepad layout.
Though I´m not speakin spanish, maybe someone can help me, if I translated the pic in the right way.
I will start left upper corner and go ccw (attached pic).

- Sustain pot will be 500k C instead of the 500k-B
- Attack pot will be a 150k-C, connected to the 150k resistor, omit the 150k resistor
- Cd will be changed to 150pF cap
- All of the 1uF / 10uF elecs will be changed to tantal caps, 25V or 35V, same value
- 1uF elec on the right lower corner will be changed to np metalfilm or film cap, value: 1uF
- 2k trim-pot may be replaced by 2 x 1k resistors
- clipping pot is connected to 1uF cap and 1M resistor, trace between 1M R and 1uF C will be cut
- 0.05uF cap in the upper center will be changed to 47nF cap
- Level-pot will be changed to 50K-B

maybe some spanish speaking member is willing to help me or somebody who already built the C4?
tia to all
regards,
Carsten

Pickdropper have a board for this project, would be far easier and have been built by couple guys here.

hi !
I did not build it but as far as I know you got the translation right...the cd cap (150pF) has to be a multilayer cap...

- Attack pot will be a 150k-C, connected to the 150k resistor, omit the 150k resistor
(do not forget the 10k resistor)
- Cd will be changed to 150pF cap (multilayer)
- All of the 1uF / 10uF elecs will be changed to tantal caps, 25V or 35V, same value
- 1uF elec on the right lower corner will be changed to np metalfilm or film cap, value: 1uF
- 2k trim-pot may be replaced by 2 x 1k resistors
- clipping pot is connected to 1uF cap and 1M resistor, trace between 1M R and 1uF C will be cut (with a 2n2 cap between lugs 1 and 2)
- 0.05uF cap in the upper center will be changed to 47nF cap
- Level-pot will be changed to 50K-B

Everything else looks fine

(I haven't built it but Spanish is my mother tongue ;))

thx to all,
especially the advice for the multilayer cap!
....got to place an order.
I built the Ross-comp some time ago and I´m wondering, if the Keeley really is "top-notch" as everybody admits.
thx guys
:)
