Have anyone made following project by stripboard?

Today I've made this one, but has quite a lot of noise compare to normal Mk2.
SCB version has white noise and if I turn Attack knob clockwise, noise increase.

I've replaced filter cap to bigger one, 47uf and also changed several OC75s but symptom stay.

Are there any tips to solve this issue?

Try to reddem those drunk items (100nF & 12K) by chastening them to the straight path (horizontal - vertical).. :icon_wink:

thank you, that's help me a lot!
also felt this circuit is more noise sensitive than normal tb2.

Indeed it does.. :icon_wink:

P.S.
I'm not sure if you've noticed that all blue wires are shielded and grounded via mustard colour ones..
(if you did so, just wonder about the reason for doing such a thing..) :icon_wink:
