The 45 (butterfly) tone control's caps values are not shown in the BOM.
Typical values for several Philcos are 10nF,10nF and 15nF for three stage ones.
I inclined to think these are the same, 10nF and 15nF.
Another matter, I noticed that when using these values, the first stage takes out most of Hi and then the to others almost don't matter anymore.
Has anyone found optimal values?
