PCB now has the AD797BRZ & L49990MA op amps and the shunt feedback resistors
changed from 560 to 390 Ohm. I mounted the large
Mundorf Supreme Caps on a paxolin board which in turn stands on a pair
of M4 x 17mm Nylon pillars. If you look at the top picture you can see
the two extra holes I drilled through the board to fix the pillars. I
also had to looze the PCB mounted terminal block for the power
connections as it is inaccessible, so I soldered leads to the board and
have an in-line terminal block for easy disassembly.
