[Amps] Alpha 86

[Don Knight]

Hello to all,
I have just purchased an Alpha 86 amplifier that is supposed to be in like new condition inside and out and working perfect with full output. This is my first Alpha amp and I am interested in any pros/cons that I need to be aware of with this model. I'm courious about all the talk about the PIN diodes being weak in this one. What if anything do I need to do to protect these from being a problem? Do I need to keep some spare fuses on hand for this? Any and all help welcome.

                                                Thanks,Don
