Need advice on Unico 12AU7 tube rolling


Dear all,

I am using a Unico CD Player which uses 2 X 12AU7 (ECC82/5814) tubes. Somehow the stock tubes seem to be quite dull and lifeless. I wanted to try changing the tubes. I prefer to have more detailed sound with more clarity. Can anyone please advise on :

- What type of tubes can I try to get more lively and detailed sound ?

- Also, how can I change the tubes in Unico CD player (any procedure to follow ?). I am totally new to tubes.

- Can I get some links to where I can find some beginner info/guidance on tube rolling ?

I will highly appreciate any experiences with tube rolling with any Unico Amp/Pre or CD since most of the Unico products are using the same ECC82 tubes.

Kindly advise.

Thanks in advance.

I like the sound of Brimar 13D5 tubes in my Unico. They are a 12AU7 type tube and are NOS, which stands for New Old Stock. You can find them on ebay, but a more reliable source might be Tubemonger.
