Ticking noise in Audio Research Reference CD7

hello Amusb , before the power supply upgrade I already replaced all the 6H30P tubes by the DR versions .Absolutely worth the price , more dynamics .After the power upgrade I
have now two DR tuhes as spare , and directly replaced the penthode regulator tube by a NOS Tungsol 6550.Wow another step forward heavensgate .So DO THE POWER SUPPLY UPGRADE.
Regards from the Netherlands Hans

hello Amuseb send me an Email at jg.kaspersen@kpnmail.nl
I have pictures to install the power supply upgrade

hello Amuseb , not interested , if you can do the upgrade yourself by bying the parts needed , or know somebody who can do it for you , you will save a lot of money , as I know that ARC France is asking crazy prices ( same as in Germany )You will need two resistors , a tubeholder ,a 6550 tube and some wiring .Time to install about half an hour .I got the upgrade as service in Holland , so i 'm able to help other ARC people .BTW I don 't sell parts .
Regards Hans ( Netherlands )

Hello Amuseb , as I think you have a mechanical problem , you can order only the mechanical part of the assembly ( called VAM 1254/21 , source daisy-laser )The PWB ( power control board ) original stays in your CD player .Remember
the laserunit is very sensitive to static discharge , but can easely be done by somebody who knows to handle.So no problem with the CL16 clock signal

hello amuseb , saw on the layout of the powercontrol board of Philips that there is an optional 16Mhz connection , this is the one ARC is using , It says in the document :
configuration option connecter X1007 not stuffed ( default )
connector can be stuffed if 16Mhz is needed.In your case you can use only the mechanical part of the unit , and still use the ARC board .
