Hi batty, I purchased 10 of them from Arrow in the US, big order - all of $3.30 USD and was delivered no charge here in NSW in 3 days by FedEx with tonnes of paperwork. I have no idea how they made any money on my order at all. But another source to use apart from Mouser and Digikey who both have a minimum $60.00 AUD order value to qualify for free freight worldwide.

Yes X, I made a bit of progress on the Melbourne’s this evening. As you know, the boards are dense so it’s a slow go to minimize a chance of mistake. The stuffing guide you posted is a big help for the parts orientation.
Since these will be exclusive to the Yarra, I’ve eliminated a few input/output parts and will install jumpers.

Hi Gary,
The part is a Fischer Elektronik SK95-25 that RS Components carries.
I do not know the cross reference part number for a heatsink that Mouser carries. Looks as if you can use the aluminum finned TO-220 sinks that X is using. Check his posted pics of the built Melbourne.

Regards,
Vunce

So Arrow does it again! This looks like the one that seemed to be unobtainable here in the US.

Very nice work, Vunce!

When you get a chance, please let me know what the max Vpp output the YARRA can make (33k load) before onset of clipping? This is with the 22V 35VA Talema’s. I am getting about 52Vpp and could use more. This is where your new O-scope is going to come in handy!
