Thanks for letting me know - did that really take a month to get to OZ?

I was interstate for a couple of weeks, so I think it only took about a fortnight in the end.

Another option for a power supply for this amp if one wanted to use a linear supply would be the new Mark Johnson/Gtose cap multiplier. Beautiful layout by Prasi. This cap mx board has advantage that there is a pot to adjust dropout voltage from 1.3v and up to about 2-3v. So one could set perfectly balanced upper and lower rails at +/-18v.
