I will be building an Etherwave Theremin using the schematic & parts values from the "Customizing, Hot Rodding" document. I have searched through the forum posts & still have some unanswered questions, specifically about the inductors in the Volume Antenna circuit.
Photos I have seen of the current Etherwave show only 3 inductors for both the Pitch & Volume side, with some posts on this forum calling out the Hammond 1535G 10mH coils for the Pitch circuit, but I have not found any posts specifically saying to use Hammond inductors on the Volume side, or to stay with the Miller coils called out in the original Electronic Musician article.
Here is what I intend to use, please look these over, and correct me where necessary.
L1, L2, L3 Hammond 1535G 10mH
L4 ---NOT INCLUDED----
L5, L6, L11 Toko 154ANS-T1017Z 47uH adjustable
L7, L8 Hammond 1535B 2.5mH
L9 Hammond 1535D 5mH
L10 ---NOT INCLUDED---
L12, L13 Bourns 77F470J 47uH inductor
L14 Bourns 77F220K 22uH inductor
C1, C5 3300pF Silver Mica
C14 1800pF Silver Mica
Cheers,
Steve
