It really sounds like you need to look into some of the noise mods that have been developed for the RPTR, Zoe. The first was the power supply replacement, developed by Peter Toms at Condor Electronics up in Seattle (who may be the person your friend was referring to earlier). Just regulating cleaner power reduced the noise by a few dB's. Then, a fellow in Massachusetts developed a internal mod to reduce overall noise, with a mind toward reducing the CFC card noise specifically. From what I understand, the circuitry for the CFC (as well as the circuit for the front side guitar input) is too close physically to the output stage and produces unneeded noise. This mod disables the front panel input entirely, and buffers the CFC stage resulting in quite a reduction in unit noise. Lately, I've seen Peter Toms announce that he figured out a new mod which incorporates both his improved power supply along with similar internal modifications to the unit. This one supposedly reduces output noise by up to 25 dB(!). Finally, a well known but quick-&-easy workaround to the "CFC clicking" problem is to simply use the RPTR's digital SPDIF output which, from what I understand, bypasses the amplification stage as well as the noisy circuitry. Of course, the caveat there is that you actually have to have a mixing board or adapter to plug the digital output *into*. Good luck with getting the noise tamed. I seem to have gotten lucky with my RPTR, and don't seem to have the same level of noise you're experiencing (but there is still some noise, though). I may send my unit in to Peter for the mod anyway, just because I'm a fidelity snob. ;) --m. -- _______ "Now Simulcast on Crazy People's Fillings"
