Cyrus 3 reconfigure for use without PSXR

[tubenut]

Can anyone out there tell me what I need to do to re configure a Cyrus 3 amp that was set up for use with aPSXR back to standalone use?
I am sure I can easily do this, on the old ones you used to remove some fuses for PSX operation. How does one do the change on the Cyrus 3?

TIA

Hi Guillaume,
Changing the cyrus back to standalone operation is easy, there are four lug connectors next to the toroid. reverse the positions of the yellow and blue wires, then reverse red and grey.
voila! put the lid back on.
good luck

I am gonna try it now once I have logged off and packed away the laptop. Thanks a lot, I really appreciate it.

Tubenut,

Why do you want to ditch the PSX-R? The sound quality should be much better with it. I have been looking for the circuit of the PSX-R for my DAD3Q if you have it!

First of all, sorry for the bump of the very old thread.


Does this procedure also work for the Cyrus IIIi ?
...or all Cyrus 3+ integrated amplifiers?

....and isn't there at least two specs/versions of the PSX-R ?
For which spec of the PSX-R is this modification-procedure sufficient?

Thx Sonusthree.

However, after doing this mod does the amp work with all of the different specs of the PSX-R?

This MAY be useful info:

The original PSX is a fixed +-40V and +-18V supply for the Cyrus 2 and PCM2 and a funny bass amplifier thingy.

Please don't take my word for it but I believe that the earlier PSX-r is fixed voltage and the later model has clever circuitry to detect which voltage it should supply. Seems like this is the only one to use with the Cyrus3 & 3i.

Here's a link to the later model (variable) which doesn't seem to be compatible with the Cyrus 3 or 3i: http://www.cyrusaudio.com/product.as...D=15&text=spec

Compatibility
Integrated amplifiers - Cyrus 8, Cyrus 8vs, Cyrus 8vs2, Cyrus 7, Cyrus IIIi, Cyrus III
Tuners - FMX
Pre-amplifiers - Cyrus aCA7, aCA7.5, Phono X, Pre, Pre Xvs, Pre vs2, DACXP
Power amplifiers - Cyrus Power, X-Power, SmartPower, SmartPower Plus, 8 Power
CD players - Cyrus Discmaster, Cyrus Dacmaster, dAD3, dAD3Q, dAD3Q24, dAD7, dAD7Q, CD7, CD8, CD8x, CDXt
Surround Decoders - Cyrus AV master
DVD players - Cyrus DVD7, DVD8

regards,
Martin.

Hi,
I have heard that there are two versions of the PSXr as well as the original PSX.
I don't know what is different between the two r versions, but I believe both have voltage detection, auto power off and adjustable output.

Isn't it a bit weird that Cyrus didn't name them so one can clearly distinguish which is which?
Like PSX-R and PSX-R2 or similar....
