I finally have my BA to do the PX25 modification along with the BL63 modification.  I also got
the B4/Ux4 socket.  I have tried several PX25's Osram and compatible with excellent result.
I have tried the Osram PX25 globe, Mazda PP5/400 and Radiotechnique F410.   I like the Osram
PX25 for audiophile and classical music,  Mazda for all round and the F410 with pop and rock music
like Pink Floyd.  The bass response from F410 is the best I have listened especially with the LCD3.
I would like to encourage about the PX25 modification and getting the PX25 or compatible , though
difficult to get is a worthwhile and may not be more expensive than the current 300B or PX4 by much.
There are several PX25's or compatible to choose.  Here is what I have and the price range from 800$
to 1500$ / mint or NOS pair.
1. Osram PX25 globe (there is also ST type, tubular type)
2. Mazda PP5/400 globe
3. Radiotechnique F410 or TM-BF10
4. M.P. Pedersen U4 E8
5. Tesla RD27AS
6. VR40  (earlier version of Osram PX25)
7.Tungsram O15/400, Tungsram PX25
8. Mullard D024
I don't have the Mullard D024 and if any friend have good access to the Mullard D024 please let me know
Thanks Purrin and Craig for let me know about the PX25 modification and B4/UX4 adapter

Has anyone tried the TJ PX25?  I understand it is warmer than the KR PX25 but is NOS the only way to go?  I am considering the PX25 vs an AVVT Px4 and am a bit concerned about the price of the PX25 vs the risk of getting a good pair.  It's all about the sound, though.
