OK - just checked all that pca suggested.

R2 is 22K as per instructions not 220 (see earlier post)
R14 is definitely the 200K according to the colour bands but measures 155K in situ.
R15 is 100K
R24 is 10K

Pin 7 of the IC7 CA3140 has only got 0.07V on it not 9V.

Does this help narrow down the problem?
