where I can buy tubes to my ALLNIC PRE (3A/110A and 3A/109B)

Two words: Brent Jesse

+1 @mwood - what he said. I’ve gotten several dozen pre-war tubes from him over the years. No issues, and they out perform new production any day.

hi 

thanks for all the quick responses. I’ll try with the website you mentioned.

I will try also through the dealers ( I try with kevalin audio, waiting for their response)

thanks again

Kevalin should be able to help you. John there is very communicative. 

Try Brent Jesse, if he can't get them, I am sure he can give you places you can get them.  He is awesome!
