Asking £99 per pair (power supply and amp) plus shipping. Discounts if you want to buy more than one.

To complete each amp board all you needs is:

  • One ATS-TI1OP-519-C1-R3 heatsink (available on mouser, costs just over £5)
  • 2 pcs OPA1656 or LME49860 on SOIC-8 to DIP-8 adapter ENIG PCB - readily available on the internet
  • 4pc tank caps: 1800uF 63V low impedance (e.g. panasonic EEU-FC1J182, about £2 each)

Plus other ancillaries and chassis etc... which are not included.

You will need to make the following easy amend to the boards as TICore260BTL Version "V1A" has a small fault that when right channel exceeds certain power output, the module goes into protection mode. This is overcome by lifting C17, then connect the ground of C17 to ground plane on C16. (Picture attached)

Good performance from these. Any questions please ask.
