I just put in more options for the 'Rare' Parts Kits. They have all new components the only differences are the 2SC1583's and the 2SC2291's are used in Options 1B, 2B, 3 and 4. There is nothing wrong with used components as long as they are tested and work correctly and within specification.
I have torture tested some (including soldering and unsoldering them 5 times), then run them for a month to make sure that they are like new, and to be honest, there is no difference, between the new and used ones except the leads are a bit shorter.
The differences between the five options below which all work as well, and have been tested on the forums (you only need one option for each x0xb0x):
Option 1A and Option 1B: The same transistors as an original TB303 Bassline. The only difference is that 1B has a used and tested 2SC2291 and 2SC1583's.
Option 2A and Option 2B: The same transistors as a later model TB303 Bassline. The only difference is that 2B has a used and tested 2SC2291 and 2SC1583's.
Option 3: The same transistors as the original x0xb0x. With a used and tested 2SC2291 and 2SC1583's.
Option 4: A mixture of the same transistors as the later model TB303 Bassline and the original x0xb0x. With a used and tested 2SC2291 and 2SC1583's.
Please see the first post.
