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

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

John Kim.   KS Park collaborated with Kim over the last 5 years regarding the:

HL2, rs242, 3A and 300B. 

This is a relatively new company but already has three versions of the 300B that perform.  There are many great tube companies out there and some I especially respect.

Stradi has excellent customer service and I personally buy from them.  (KA has no affiliation with them otherwise.)

Kron is another consideration. 

thanks again for all the quick responses.

I’ll try also at straditubes

@yossie4 have you tried the Straditubes, are they good compared to NOS? I am looking for a pair of 3a/109b tubes but the NOS tubes are so expensive. I remember seeing them several times last year for around $100 each but they are 4 times more expensive now.
