BAT VK 5i and tubes, how to chosse?



I live in a distant Brazilian city, I have one BAT VK 5i with sovtek 6922 tubes. I would like to know about 6DJ8 amperex bugleboy logo, made in Holland( $105/pair), and 6DJ8 Amperex Orange World Logo Made in Holland($30/one)
Do you think they match with my BAT? . Some people
said to use sovtek 6H23 in place of sovtek 6922, even so are cheaper than the 6DJ8 amperex, but I think
that valley to pay for better quality. Which the best choice? is there any DANGER to BAT with 6DJ8?

I'd post this is AudioAsylum.com under amps/pre section. Victor, one of the BAT owners, and the designer, usually replies.

I have Amperex 7308's Orange globe logo in my BAT vkp10se phono stage. Sounds wonderful...replaced the stock sovtek 6922's...
George,

I have found that the BAT preamps don't care for the 6DJ8s. I have tried the Bugle Boys and they were fine for about 10 minutes and then things got noisy. If your determined to roll some different tubes into the 5i I would recommend a 7308.
You may think I am joking here, but I am not. I have had good luck with Sylvania/Phillips JAN 6922 which you can buy from PartsExpress.com for $7 each.
The Phillips JANs work fine, as do the Sovtek 6H23s. Better 6922s or 7308s work even better. If you are interested in some 6H23s with very few hours on them, contact me off-thread and maybe we can work something out.
