SX-Amp and NX-Amp

I built a 6N1P tube line stage pre that sounds pretty cool but has tons of gain. Maybe too much for the NX.

Quick shot of the amp now, in the equipment rack, the top still off so I can check on bias and offset and tweak as it settles in. Now with 4 x 15,000uf 63 volt Kendeil caps. I'll yank the amp back out of the rack when I get a chance to get some better pics. I was in a hurry to hook it back up and listen for any improvement with the new caps, which there was...
An externally hosted image should be here but it was not working when we last tested it.
 
Q.
Is BAS21 necessary for D4 & D5?
Could 1n4148 be used? Peak current with 35Vac is ~16mApk, the BAS21 is rated for 200mA and 1n4148 is rated for 75mA

Q.
D2, D6, D13 & D14 are BAS21
Is there an alternative diode that satisfies duty?

U1 is shown as both pdta144et and pdta114et?
Which is correct, the 47k, or the 10k?

Does R2 22k exist?

R21 & R22 listed as 3 off 2.7K but is on the PCB as 2off 5.6K
R28 & R29 as 120 Ohm. The PCB has them as 150.

Line 28 shows 2 off and should be 4off
BOM list in the pdf file is correct dont look on the PCB parts marking as it have some small variations when compaired with first version.Yes SC is smd LED light
The BoM cannot be correct.
