Zen (basic) and BoZ PCB

[ThierryM]

I have build last year a (basic) ZEN and Bride of Zen ampli/preampli.
Both are working perfectly.

I would like to share te PCBs that I have designed for these realisations :

The files are attached.

Note that :

For the Zen PCB:

1) The 0,33 Ohm resistor has been replaced by 3 x 1-Ohm resistor (one resistor can not be mounted, in order to reduce the power and the heat of the ampli).
2) The PNP transistor is a standard BD140 (in place of the MPSA92)
3) The PCB of the Zen amp has the size (and is mounted) to fit in the central "channel" of a common low-cost heatsink for (TO3 transistors).
4) Are NOT on the PCB : The output capacitor and the power supply.

For the Bride of Zen:
The power supply is not on the PCB.

For both PCBs :

- Reduce the size (at printing) to adjust on the composants dimensions.
- Be carefull in the "mirror" symetry.

Many thanks for this very good ampli.
