Q&A（Please review carefully before purchasing.）

Q1 ： Are these genuine Sparkos Labs op amps???
 A1 ：Yes, 100% genuine Sparkos Labs SS3602. Fosi Audio is an authorized dealer, comes with original packaging and riser

Q 2 :     Does 1PC mean 1 op-amp or 2 op-amps?
 A2 ： 1PC=1 SS3602 Module(2 Independent Op Amp Inside) = 1 DIP8 circuit board. Each board contains 2 independent discrete op-amps. Electrically, it's equivalent to one dual op-amp, directly replacing the NE5532 or MUSES02 pins.

Q3 :     How many boards are needed for a BT20A PRO amplifier upgrade?  
 A3 ： A complete upgrade of both left and right channels requires 2 boards; for a single-channel upgrade, 1 board is sufficient.

Q4 :    How many op-amp units are included in the 2-board kit?
A4 :    Each kit contains two boards, each with two op-amps, for a total of four independent op-amp units, enough for the entire system upgrade.

Q5 :    Can the original dual op-amp chip be directly replaced?
A5 :    Yes, it's a DIP8 package, with pin definitions compatible with NE5532/MUSES02, allowing for non-destructive through-hole replacement.
