Several typos crept into Ian Hegglun's article

Several typos crept into Ian Hegglun's Vol 4 article "Towards a reconciliation of measurements with listening tests".

Some of these, notably fig 6 and fig 10, have been addressed in Ian's reply to Burkhard Vogel's letter.

The remainder are listed below:

1. page 39, Fig.5: CCIR-468 weighting filter circuit: L1 should read 12.88mH and C2 26.82nF and L2 in nH.
2. page 41 Figure 8. Filter banks for evaluating twin and triple A-weighting using the Total Difference method: change: R3 to {RL}

Also note that Ian's Power Amplifier Kalkulator spread sheet PAK 1.0-NM along with the User Guide and the LTspice circuits can be obtained by email from Ian at ianhegglun01@gmail.com
