Another compact GainClone (GainBlock)

diabloid · 3rd July 2010, 08:57 AM

I build several GC, but I always wanted to use benefits of small circuitry to make it as small as possible. Final result was by using insulated transformer, mounted on top of case. The results are on the pictures.

I hope it would be interesting for others.

If anybody needs, PCB just let me know. It is practically point to point design, pcb used only in order to preserve chip legs, since I manage to brake it once and one lm3875 went to rubish bin.

This based as mentioned on LM 3875. It also have passive preamp with 2 attenuators (Lorlin switches with resistors chain). Currently it drives B & W 601 pair due to my laziness to finish my DIY paper cone speakers:-)

Cambridge is another great company:-) I can built DAC, but it would not look as good while savings will not be drastic. This little gem worth every penny, maybe tube buffer in the future will be the only upgrade to cambridge magic dac:-)
