hi.
on moogarchives i found the schematic of the beautiful melodia. it does seem to be similar to the published article 'transistorized theremin' in 1961. unfortunately the component values are not really readable. i now have done the chassis, and the soldering is being finished, but i have problems with the volume-section. maybe somebody could provide me with the values or a better scan just of the parts list?
thanks

I don't need the values anymore.

Dominik,
I am thinking about building a melodia. I have the magazine article. Do you have any tips, advice, or modifications regarding the melodia?
thanks,
bret

hi bret,
for i just wanted the "real thing", i have not incorporated any modifications but one highly recommended: a fixed power supply (7806). it still is a mimosa, sometimes when i put it on the tripod some adjustments have do be done to the coils. behavior and sound hardly depend on the pitch-coils, where i use those small blueish plastic-housed epcos ones. for the variable coils i fabricated something like the originals with my turning lathe. on each end of normal screws i lubricated single available ferrit rings. many different settings are possible and i finally stopped by a range of about just 3 octaves but with a pleasing sound to my ears. the range of volume control is just about 5 centimeters by using the metal plate..
good luck and even more patience to you,
dominik
