F5m kit

It's all gonna be ok. We just have to hunker down, tighten up our boot straps, huddle together for warmth, and sing joyous music while waiting for the darkness to lift. Not long from now we will all be merry as the postal service delivers special presents from Papa to Greedy Boyz all over the world. From that day forth March will be known as "F5m Month". Soon we will all be sharing our build stories, listening to glorious music, and looking back fondly of this time full of excitement and endorphins. "The good ol' days" we'll say. Good times. Good times.

I thought I read somewhere that the Completion Kit would come with all semiconductors; even better, with MOSFETs that were selected by Nelson, to provide that special harmonics signature.

It is quite possible that at my age I misread it, or imagined it. In this case, the blame is on me and I apologise for any confusion that my post may have created.
 
In store searching for "f5m" will lead you to the sold out items.

Leave it to the German guy to use practicality and a straight forward approach. I'm slapping my hand to forehead now. In my "brilliant wisdom", I figured I could find the super secret F5m web pages by tunneling through a virtual private network alley to the Dark Web. It was there that I hesitantly brushed the perverbial 'digital shoulders' with numerous shady individuals as I asked around for a key to the vault. I finally bumped into an audiophile hacker with the alias Sixlimasix, who was able to provide me with the hypertext transfer protocol uniform resource locator codes. I was "in", but I did find it odd the hacker didn't want cash or bitcoin for his services, and instead insisted on being compensated with Toshiba P-channel JFETs. Anyway, learn from my mistakes. That search bar idea is the safer approach.

Hi I need some advice. I have built an F5 some time ago and liked the sound very much.

My speakers are vintage Altec Santana 879a and Valencia 846b so that I am sure it will be very difficult and costly to get spare parts.
The F5 andF5M have no protection circuits. Are protection circuits not nessessary with this design (will the amp die silent) or will in case it blow up my speakers?
