Most of the time you have to change the belts and clean the heads. But it's always like a band for the hardware.
It's less fun and prcis that are homologous Monitor Report 4200. For VU meter is small. And the head of less accuracy of all writing.
Let's say if the blast did not GNE you it will do.
Otherwise you have to go in 4200 for more quality. And then to nagra IV-S, but it's more than double the price!
