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

audiotubes.com

Try the above, hopefully they have your tubes.

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

+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
