Yes, still available. Ordering info can be found in a first post of this thread.

Default F5 Boards ordered

Peter

I have just done a Paypal payment.

If I cannot source good parts locally I might approach you to quote for parts as well.

I am looking forward to see how the F5 compares to my DIY Aleph 30?

Regards

Jozua

Default Any parts preference

Gentlemen

Are there any recommendations re which brand of resistors (Mills, Dale, Riken etc,) works best with this board. It is so small one could just as well go over the top?


Regards

Jozua

When it comes to standard resistors, I recommend Dale CMFxxxKQFCT available from DigiKey. If you want something better (which may not make much difference anyway) you can go with Caddocks MK132 or Vishay S102.

As to power resistors, blue 3W Panasonics fit the board, but I'd reather go with Mills 5W (available from percyaudio or partsconnexion)

Default MK132 on the heatsink

On the amp most recently presented (post 2800) there is an MK132 mounted next to the output device.

As you know, and expect, I cannot figure out which resistor this is and why it is there.

Would you mind telling me?

AS ALWAYS, thanks very much,

Those were actually MP-930 used as series resistors between filter caps. Didn't work out as expected and I switched to Mills mounted directly on the caps.

Luke S., you tried to contact me yesterday, but my email reply bounced back.
