K80 build?

[jaxx]

no one have any information about K80 amp?
i know that is a special ed. of komet amps, but nothing more.

it is a K60 or K50 inspired?

sure it have three 83's and two KT88, i'm searching on the web but i founded no internal pics at all.

i've built one, with k60 circuit and oversized HT (like 560vdc on 5k8 or 4k5 OT primary), but it have not the punch of my k60...

I'm guessing the k80 has the k60 preamp but the k50 poweramp with kt88s (220uf caps; ss rectifier; possibly 4k8 OT)

thanx gng04,

have you got others pictures?
especially for the two boards, many thanx.


seeing on photos preamp is similar but not the same compared to the k60 one, on the 3rd gain stage i might have a 220k anode resistor, and the PI grid stopper seems to be a 100k and not a 220k like k60.

the reservoir power tubes plates caps seems to be two 220uf in series (one on up the board and one under), i cannot see the second caps value (g2 supply), i think they were two 80uf mallory's, like k60.
