Parts list and locations
Capacitors
C1 10 25v small green bulb
C6 471 flat brown
C14 *7501 brown bulb
C16 & C18 221 flat brown x2
C19 22uf 50v electrolytic can
All other C positions: 104 tantalum cap x12
Resistors
R4 & R10 Brown Black Brown 100 ohms x2
R9 Brown Black Red 1k
All other R positions: Brown Black Orange 10k x7
Questions
1) I received a larger green capacitor with markings 2A104J but I have no idea where it should go as I don't see this in the photo. Is this really part of the kit? If so, where does it go?
2) Please confirm where these capacitors should be located as the photo is not clear:
C1: 10 25v small green bulb
C14: *7501 brown bulb
3) The photo shows transistor, but I did not receive one in my kit. What is the part number of this?
4) WRT the socket at B1. Is the top left pin, connected to second pin by a trace on the back of the board?
