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

Yes, definately, go for it.

Thanks guys.
Anyone knows of a reliable and reasonably priced source for the DR version tubes?
Cheers from Paris.

Amuseb ...

ARC has all the tubes you need in stock. Also, as others have said, the power supply upgrade is well worth the nominal cost. Get the upgrade and new tubes at the same time. Hmm ... I wonder what the shipping cost will be from France?

Thanks Oregonpapa.

Do ARC also sell out of manufacturing tubes such as the DR or the NOS 6550's?
I thought they were only selling tubes that are still available from existing manufacturers and their current tube types.

It would cost a lot to ship to the US and back and the local rep in France takes 450 euros for the upgrade (a hefty equivalent to 600 USD)...
Again , it's not a ton of money in the perespective of a good hifi system but yet it's not a given either.

Thanks for anymore comments if one has them.
Regards.
