I have 2 complete amplifier PCB (one stereo set) of load invariant amplifier PCB modules for sale.
They offer ultra low distortion in 8 and 4 Ohm loads.

They are the complete, original and fully assembled kits I bought from the Signal Transfer company a while ago.
They work & measure withing the published specifications.

To make a full amplifier, you only need to add a power supply (+/- 25V till +/- 45V) and a heatsink. I also have a suitable PSU PCB and heat sinks if you're interested.

See
The Signal Transfer Company: Load-Invariant Power Amplifier
(see post #3 for pictures of my item)

Price $180 USD for the pair by PayPal including shipping by airmail.
