Stock Tubes on Cayin TA-30?

yeah i'll have to break them in a bit. I did find out the stock tubes are Valve Art's EL34

it's just you get different answers for tube break in period. some say after a couple hours, some say 30-50 hours.... i'll just put them in and hit repeat for a while and evaluate them later. see what happens.

and i am definitely enjoying this amp. it will be my last for a long time. to only other piece left for me is a great redbook CD player for less than $500

Has anyone rolled the Electro-Harmonix 6CA7/EL34 Big Bottles?

dsockel,

i'd like to know that as well..... if someone can comment on the sound from the tubes you mentioned....

I too replaced the stock tubes with Svetlana EL-34 Winged C's and the sound has much improved. Compared I found the stock tubes much too bright.

I'm thinking of buying a used, unmodified TA-30,
is it awkward to bias them?
