Terrible speaker to pair with a 300B or 2A3 unless you were to find a Push Pull. You might find a used unit from Opera Consonance that may meet your needs.
The M100S Plus is a 22w Push Pull using 300Bs and is a darn good sounding amp. It would be in the right price range for you used.
Another option would be the Consonance Opera Reference 5.5MKii which is 18w. Not huge power. If you can find it use, it will be in the $1100 range. New, it can be had for $2000 even with the current Chinese Tariff situation.
You would undeniably be better off with a more powerful amp A used Rogue Cronus Magnum would be a better choice but if you are dead set on a 300B, those would be your best options.
2A3s are the ultimate tube in terms of detail IMO. 300Bs have the best mid-range which is lush and addictive.
