Default Heatsinks are always a good idea...and they will not increase the amplifier costs

As you can use, even, a Coke can as heatsink...just cut the aluminium foil with a scissor, make it " L " shape and attached into the transistor.

regards,

Carlos

Well..we are all brothers in the reality.

Default I love the original green from the fiberglass boards


Yes..you may call it yellow before receive some paint.

But those boards can be found in many colour options.

Marantz made the Model 1200 amplifier using blue boards.

" Dx amplifier can be ordered into your boards supplier in different colours "

Carlos
