Default ★★Another Donation: Free Power Supply PCB For JLH Amp, including components!

Hello we are ready to begin another donation to the forum members:

The Free Power Supply PCB For JLH Amplifier

It's designed by a nice Australia guy Alan Cooker. We tested it and the result is very positive. Alan is happy to share his design with all DIYers so we designed a small board to offer for free.

We'll not only offer free boards, but also all the passive parts including:
2 x 470u/35V capacitors
2 x 1000u/35V capacitors
2 x 330 Resistors
2 x 2.2k Resistors

As an option you can also get all the transistors at a very low price. Just click the check box in the above link.

Thanks and happy DIY

No need 2pcs..1pc is enough for stereo. It can source 4A with 2N3055. not so much heat since the voltage dropout is less than 3v
