CDJ3000 spares

We undertake Pioneer DJ / Alphatheta repairs in Cape Town South Africa. We have been experiencing warping of the Jog Wheel Jog Dial when the CDJ3000's are used at outdoor events when subjected to the sun. When this occurs, the CDJ3000 will not function in Vinyl mode. To rectify this, the Jog Dial DNK6778 and Sheet Switch DSX1139 need to be replaced.

The problem in South Africa is that there is no stock of either from the Distributors and no ETA for either. The Distributor has been advised by Pioneer / Alphatheta spares that their supplier is unable to supply these spares currently. This is unacceptable as CDJ3000's cannot be used as intended.

Can someone at Pioneer DJ / Alphatheta investigate?
