Hey guys, I'm interested in getting into a Magnum S9. Used looks to be the only way to go, and I'm seeing that the earlier models used bipolar 1969 finals, newer models used mosfets. I've done a lot of reading on this, but do not fully understand the good and bad between them. Seems some guys swear by the older models (better reliability/performance), and others are happy with the mosfet models. Just looking for some insight from minds more familiar with this stuff about the good and bad between them? Is it worth seeking out the older model, or will any well taken care of unit serve me well? Also wondering if there is any info on the future of Magnum and if new model radios are down the road?
