So…. BOTH VT1s have been changed, back to their correct (new) BC186’s
Now the fault is back to square one 🤷♂️ Crap output on only one channel… it actually worked better with the incorrect transistors fitted! What ever is going on?
The only thing I haven’t touched is both VT2… which are ALSO BC186s? Could these have failed too?
I've honestly no idea where to go next...... I've ordered some more BC186's to shove in both VT2s, aside from that, pft.
