Please help! Looking the schematics for: K-AMP Integrated Power Amplifier DIY Kit

Please help! Looking for schematics for: K-AMP Integrated Power Amplifier DIY Kit

I have a pair kits for the:

K-AMP Integrated Power Amplifier DIY Kit
ref Krell KSA 100 (Single Channel)

Unfortunately I bought these stuffs many years ago and I lost the schematics and parts list what I need to build them up...

Please help me if you have it...
Many thanks in advance!

Just put the transistor pair in a search
After that check for similar circuits that use the same pre amp.
Can't be a very different circuit.
And you can work backward from an already made circuit.

I didn't find any helpful information 🙁

Many thanks for your helping efforts, but I'm looking for the 100% same schematics for build my kit.
This kit doesn't contains any diodes at all. (no zener diodes too)
I need to know all parts exact positions and values on the PCB, max and recommended supply voltages too.
So if someone has the same, please share that with me.

Good quality set. Large PCB power supply. Small PCB power amplifier (1 channel). Reverse engineering is needed. Make a table of connections (element number and its connections). After conversion, get the schematic. According to the diagram, you can establish the correspondence of the denominations of the parts.
The vendor trades Rasberry and Arduino.
#1 1. Design use Krell KSA100 classic power amplifier circuit as blueprint
2. Maximum output power can reach 70W for 8 ohm output loading
3. SANKEN high power (200W) transistor 2SC2922/2SA1216, double emitters with low output resistance (70m ohm), high linearity and bandwidth (50MHz)
4. Built-in voltage regulating circuitry, come with Nichicon high class KG series 10000uF/63V for power filtering capacitor
5. User can easily modify this DIY kit either series or parallel technique to deliver even higher output power

Power transformer is optional and it can be bought from our store (Toroid Transformer 270W for Tube Amplifier)

Sorry - maybe this is my fault - but I really don't see how can it helps for me?

Your linked schematics is an capacitor input coupled and "FET-end" based amp...
My KIT is an DC coupled input, full transistor based amp.
