RJM Sapphire

Another weekend, another project.
Started on the RJM sapphire headphone amp this weekend. Having a bit of trouble with the transformer I ordered. According to the BOM they specified a Triad 25VA unit.
I got them from Mouser and it was huge, the wires were unwieldly and I didn't think I would use them
Looking at the pics posted by RJM, they used Amveco, which is my normal brand.. DOH!
So off to digikey to order yet another set of transformers..
Also need to figure out if I would use the bridge rectifiers I already bought, or use Peter Daniels rectifier PCBs and use the MUR280 instead.. the latter will be faster and cost more.. the former might not perform but it's cheap
