CW, What part numbers did you have for the transistors? Some of these boards don't have legible writing on the transistors. G

LOL, the transistors I purchased were the ones that you (GGG) identified in 2012 in this thread. (THANKS!)

I could not see the markings on the original transistors while they were on the board. As I removed them, I could see they were there, and matched your 2012 descriptions. The board I asked about in 2012 did not have marked transistors.

The attached document contains what I have so far:

Part Num	description	cost	per ten	25	50
A27745CT-ND	AMP # 42067-1 female quick connect	0.12	1.12	$2.09	3.59
A24783CT-ND	AMP # 62122-1 connector quick connect tab	0.21	1.98	$4.21	7.37
2N3904CS-ND	2N3904 transistor (req. 2)	0.41	3.22	$6.60
2N4403CS-ND	2N4403 transistor	0.41	3.84	$8.40
