Total renew of a Vox AC15 guitar amplifier
Many years ago, I was asked to restaurate an old Vox AC-15 box amp. The device had been completely emptied, only the transformers were still on the chassis! Visually, the device looked excellent, so the effort seemed worth it and I got down to work.
Internet was not there yet and unfortunately I only came to a probably several times bathed in coffee and therefore barely legible circuit diagram. It is therefore possible that the circuit no longer matched the original device. Nevertheless, the sound of the device successfully reconstructed with unused NOS components and according to the circuit diagram shown was convincing.
