I'm new to the site, but have been enjoying the hobby for years. I'm asking for some help locating a parts list for the Threshold SA/3.9 amp. I don't know if some of you are like me, but somtimes I like building some of the older "classic" amps just to learn from the experience and enjoy the final product. I realize the 3.9 is not going to be the "topic of much conversation" at this point in time since it's about 20 years old, and semiconductor availability may be a real challenge, but does anyone have stored away a parts list and maybe even a service manual? I was able to find a schematic, but no parts values are listed. I'll be greatful for any help, and appreciate Mr. Pass and his willingness to share with the DIY community. Jon B
