Roland TB-303 Tact switch replacement

Another routine job of replacing the tact switches on a Roland TB-303. This is quite a comon fault, I suppose its due to the age of the machine and the fact that the tact switches don’t have any dust guards. Luckily we are still able to source spares (for now). I’m always happy to work on these machines since I love the TB-303. This particular model was one of the more squelchy ones, more so than the one we have in the studio. For those in the know, this is one of those that used the 945 transistors rather than the 536′s. From what i understand (through building a couple of x0xb0x’s at home) The 945 machines tend to have a more metalic resonance.  The one we have one in the studio uses the 536′s and it’s not quite as squelchy as this one.  I guess one day i’ll have to find a TB-303 for my home studio, but for now I’m quite happy with my x0x’s.
