Older amplifiers are almost always not serviced by the factory because the parts may be obsolete and they don't want to take the chance of damaging, say, a working transistor while in their care. The only option is use a substitute which may not sound as good in the circuit. So essentially you lose your amplifier and how is Krell going to compensate you?
If you are looking to get it recapped, ask Krell who they authorized or recommend (i.e., Levinson advises you contact Pyramid Audio; don't know who Krell recommends).
