Would these diodes also be found in the CA200? Or are there analagous ones in the CA200? I have the unit in for repair so this might be an opportune time since the "hood" will be open. Thanks, |

Oh no, what have I done. :-). I would get professional advice before touching anything unnecessarily. as I had parts that were faulty I may have been living with sub standard sound prior to the failure. Maybe the fix only brought my CT5 up to spec. The new parts were apparently better quality but beyond that I can only give lay mans advice.
All I know is that in my case the preamp would go through its start up process with the delay and everything but that the power light remained off. Based on the posts above that would confirm that it wasn't the diodes in the logic circuits ( that could not impact sound) as they were working while the unit was broken. I have one of the dead diodes and it says RHRP860. Then N3 13. A big F. Then AB. It's an odd shape with a metal bit on top with a round hole in it. |

..assuming it's OK to post this kind of thing. (I'm a card carrying electronics hacker/nerd. Others may suffer various afflictions if viewing component data-sheets for any length of time)
pretty standard stuff..and yea, if one or more of these fail, especially if/when used in a power supply, it's bad news. |

They are found in a any piece of audio equipment and are used to convert the AC voltage after the power transformer to DC.

The RHRP860 diode is the bridge rectifier diode. The best and fastest made today are made by Infineon and they have a recovery time of less than 10ns vs. 30-40ns for the best of the rest. |

Diode rolling. :-). Very amusing.
Still being amused by the new sound also. Love this CT5 LP70s combo. Looks great sounds wonderful. |

Chryo did not work for me in the input or drivers positions of the pr 12 but did on the power tubes.To me the pr 12 was toooo soft with 6550s and the chryo kt 120s really worked compared to non chryoed 120s and 6550s. In the lp275 both the 6550s and chryo kt 120s were different types of real good synergy with no clear winner. (chryo tubes worked well in my preamp and phono). Where it did not work it was hard and unattractive. The ct 5 is a little harder/faster(which i liked) than the act 2.2 in my experience with regular tubes; causing the act to benefit from a little less warmth and softness and be a little more like a ct 5. I want a tube pre that can do delicate female vocals and then do well with some red chili peppers also-equally well. It is nice that such good sized differences can be experimented with for such little $$$. Solid State owners wish they could make these types of customizations. You dont know till you try
