Hi. I found this rather untidy schematic for a simple pitch only theremin. I am interested in building it, because its a pretty groovy instrument :lol: , but most the ones i've seen are very much more complex.
Anyhow, on the schematic, it specifies 3x BF195 transistors, and underneath says BC182, is the first one specified in a foriegn coding system, because I can only find the BC182. Also, it says 3 but there are clearly 4 in this schematic, are they all the same?
I would order the parts I don't have (ie. the BC182s, inductors and small caps) next time I send an order. But, I'm pretty sure this being a radio frequency circuit, it cannot be tested on breadboard, is this right? And for that matter, will be difficult to do on stripboard.
