hmm, i am trying to figure it out,
could you please recheck the stripe board version, i think it has error on T3
the pinout of T3 on stripe board using Row Colum
B J is the collector
A I is the Base
B H is the Emitter
according to schematic Collector should have 9+ from battery, but there is no connection
R10 (33k) should be on Collector and Base , but on the stripe board its on Emitter and Base
getting more confused now xd
will try more in the morning. I maybe wrong cause i am no electronics expert.
