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

The 3a/109 is also called. CV 1663. Those were used pre WW II. Good luck.

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.
