Note on 16 Nov 2017 : The boards are now tin-plated. Copper thickness is as thick as before. Quality is as good as usual. The price is lowered !
This is the bare PCB of an ultra high-end power amplifier. The power amplifier is with reference to Goldmund Telos 390 integrated amplifier's power amplifier section.
The original product uses one board design for both channels.
In our incarnation, we retained the feature of one board integrating power supply amplifier circuitry for lowest rail impedance as to attain high speed and stability performance. Please see the original component board at the bottom of this page as compare to our board layout.
On the other hand, we use one board for one channel of amplifier. This provide diyers flexibility to fit the boards with their preference housings, or to make the amplifier in monobloc structure for best channel isolation.
Supply voltage : AC 40Vx2 to 45Vx2, 400VA per channel
We provide schematic and part list by email ( attached to the shipment notice on the item posting day).
This is a PCB of premium quality.
PCB dimension : 137mm x 117mm.
PCB thickness : 1.6mm, 2 oz ( 75um thickness !!) copper deposition. Surface is tin plated and two-sided solder-resist coating for best durability.
We do air shipping worldwide at US$6.00.
