Hi wg_ski,
Yes, both. Plus there are other issues that need attention. In addition there are things that require care and attention while disassembling the amp board. This is in addition to the standard issues you may run into with other amplifiers. Many amplifiers have idiosyncrasies for disassembly and you need to be aware to avoid damaging things. These can also cause failure of the output stage even though they are small, low current areas (like the bias control circuit). Even lead dress can be very important.
