Be careful, there are 4 different kinds of transistors on this circuit.  Make sure you get the right one in the right place.  After you build the VCO, it is a good idea to [[VcoTesting|Test]] the circuit after you build it, this will make tesitng (and troubleshooting, if you have to) the other sections much easier.

==== Additions ====
You might want to mount Q8 on a SipSocket, so that you can put a HighGainTransistor in there.

If you are unsure of your soldering skills, you can also mount the 3 ICs on DipSockets. Also, if in the future one of these ICs were to fail, you will be glad you socketed them! 

==== Mistakes to avoid ====

**equaliser says... ** The picture in the fab manual for the 2SK30AO transistor is actually of the AY transistor, which I soldered instead of the AO. Ignore the pic - you need the AO in the VCO.
