Can a new brand of power tube even duplicate what this pair of RCA's are putting out?

Having a difficult time finding a brand of tubes to match the wonderful low end tone this old pair of el 84's produce.   I actually pulled these old tubes out of a post ww2 era hammond organ, it was in my garage for 20 yrs.. I still cant get over the low end these old dusty RCA's are throwing out . I purchased two pairs of new tubes TAD EL84-STR  and The JJ's. Both didn't  even come close  

Was surprised about the TAD, they were suppose to have significant low freq. but compared to the RCA hey were a disappointment

 Any one have any insight on why this is, also any worthy brand suggestions to try?

Yes check out brent jesse recording, 
Or Vintage tube services. They may have some WW2 tubes.
Or early 50s.
