Custom F-2624 driver board for Sansui 7070 - pros/cons?

[JBL-L26]

Found this custom bare board listed on eBay for building F-2624 driver board ($25 board) with complete BOM for parts ($25 for all parts). Attached image of the board.
Has anyone tried building something like this?

Seller quote "This is a new replacement board. It is redesigned slightly to use modern bias transistors rather than the 2SC984 or STV3H. This is the same dimensions as the old board, and will fit nicely in your receiver. This is a super-high-quality ENIG-coated circuit board, and is unbelievably nicer than the originals."

Is it a worthy upgrade over original F-2624?
Will it affect the original sound quality?
Any other pros/cons to consider- please share.

This board is the most recent version of the F-2624 aftermarket boards. The layout is an improvement of the OEM board & the others. You have to build this board with the BOM available upon purchase of the board. It is a worthy upgrade if properly assembled and adjusted =>[DC offset, Bias & quality of work]! Building this pcb is a big project and will take time but it is a better solution than try to rebuild an original OEM board. As far as the sound quality effects? The answer is loaded with so many variables that it is totally subjective and cannot be used to make a decision to pursue.

Build it. If you do then make some comparisons with your speakers between the two. Also do some comparison with headphones, see if you notice any difference in noise floor. I don't think I have seen a thread here where somebody A/B'd two boards.
