Acquired this 1979 Italian-made organ/synth some time ago but have only just got around to having a closer look. By that I mean that I have only just started to try and understand why it fails to work properly. It does sort of work but only about a third of the keys function. The keyboard is split into bass & treble sections. At present only the bass section makes a sound. Even as a bass synth, looks and sounds great though. All very well, but it would be much preferable and useful to have a fully-working unit. The reduced price payed reflected its current state of functionality. I took a calculated risk on this as I usually have a pretty good idea how to make these things work again. My repair methods are quite basic. This usually involves fuse checking, wire jigglig, a bit of cleaning and reseating of circuit boards. For the most part I get lucky and the instrument under scutiny suddendly finds a new lease of life. However, no such luck with the Crumar T1. Lots of jiggling and reseating of (numerous) boards has had any effect at all on the treble section. This is not going to be an easy fix. Only one thing for it. I've been putting it off but perhaps now is a good time to learn to use a multimeter properly so I can actually test the components...
