Did you have a nice cold beer in your hand while sitting on the beach getting rained on?

 

[AKSA]

Ah yes X, as I always suspect of busy people visiting our sunny Queensland, perfect one day and a liitle boring the next. And you are one of the busiest people on this forum!

Enjoy your rest..... .

Is it too late to order a Yarra PCB?

Thanks, Batty.

I return from vacation tomorrow and will order the Yarra boards now that they have been verified to work. There was one small silkscreen typo that I caught on the PSU. Otherwise, all seems good to go.

I'm afraid I would find it hard to leave there.

For the preamp is 1yarra and 2 melbourne? For the complete set

 

[xrk971]

Yes. Spare Melbournes are nice to have for changing gain or for making a HPA.

Ok I am back. Will start to finalize the layout and Gerbers with JPS64 and with valuable feedback from Vunce as a Beta tester - we should be able to get a great boardset out to folks soon. I might try changing the gain on mine to 29dB tonight to get it to drive 55Vpp.

FYI here is how one commercial headphone amplifier product chooses to arrange their left and right RCA-Cinch jacks on the rear panel. Left on top, right on bottom: Figure 1 below.

Also shown is a preamplifier from Krell, partitioned into two boxes for lower noise, woo-ooo oooh (Figure 2), and finally Nelson Pass's first preamp, the 1974 released Threshold NS10 (Figure 3).

I just swapped out R118 on Melbourne for 1k (5k6 default) and now gain is 30.6dB. Actually a nice setting for my Bluetooth source to drive my MOAMOFO. Can play very nice and loud now. Sounds great.

The removable Melbourne max changing the resistor a snap. Nice ease of use / servicing.

I like right over left.....

Wow. I built my preamp with the right channel over the left. I guess it will build the YARRA the other way so it sounds better.
