I thought I would update this thread with some pics and info of my Hifimediy TK2050 V2. Power supply is the Meanwell 27VDC that is recommended for it.
This little amp has just knocked me out. I spent about $200 including amp, power supply, case and all connectors and wire. It makes a mockery of some of the big $$$$ amps I've used in the past. I'm driving a pair of modded MMGs and just can't help but grin every time I listen.
I posted a pic of the input mod I did. Removed the pot and wired the L+ and R+ to the holes directly in front of the input caps. Removed a curtain from the sound. This amp is as cheap and cheerful as I can imagine!
I then changed out the input caps for a pair of Gen1 2uf Sonicaps with a Gen2 .1uf bypass. Another curtain gone.
