Re: Cyrus 8 xpd repair with wrong part (with schematics)

Firstly a fuseable resistor A resistor designed to protect a circuit against overload; its resistance limits current flow and thereby protects against surges when power is first applied to a circuit; its fuse characteristic opens the circuit when current drain exceeds design limits. ie the fuse blow...

Re: Cyrus 8 xpd repair with wrong part (with schematics)

Thanks for the full circuit diagram. no need to check the doide voltages. The 1 ohm resistors are in the input side of a voltage regulator that supplies the power amp so not critical if 1 ohm or .5 ohm or a bit of wire. The wire is undesirable and an unprofessional repair as one looses the Fuse func...

Re: Cyrus 8 xpd repair with wrong part (with schematics)

Id need to see the full CCt. If i send you a PM with my email address can you send me a copy of the service manual . It may be that the original 1 ohm fuseable resistor has blown and someone has lazily fitted a piece of wire and sold the amp on. The wire resistance will be less than 1 Ohm but how mu...

Re: Op-amp Tweaking

On reflection, I hope I havent gone OTT when talking about back emf . For those newer members who dont understand, this analogy may help its - High School physics. An electric motor rotates when you apply a voltage to it. The current passing through the windings of the motor generates a magnetic fie...

Re: Op-amp Tweaking

Can you be sure its an op amp issue ? Ive stuck rigidly to Bruno's choice of components for my N Cores. He's got the test gear most of the smaller boys dont have - and knows how to use it. I did find that minor tweaks to my speaker cabling allowed me to get the sound I wanted -which surprised me giv...

Re: I'm running Everything On Batteries, Power supply

I concur with what mojo has already mentioned. The two issues mentioned so far are how true is the SINE wave generated and what noise components are are running on it due to the electronic conversion process in your DC-AC Converter, compared to your mains supply. There is a 3rd issue where I would e...

Re: DACXP+ balance control

I was going to provide a link to some info on a balance control using conventional resistors and log/antilog pots but it gets into techspeak and it also points out that much of todays equipment uses software to control volume and balance. I dont have a DACXP and its impossible to comment unless one ...

Little used, I changed the IEC mains inlet connector to rid it of the Cyrus cheapie where the cable fell out rather easily I dont have the ...
