Used as a replacement part in a Laney LC 15R

By: on 12 November 2022
I used this audio transformer as a replacement for a faulty O/P tranny in a Laney 15 watt amp. It is pretty much a perfect match. The original one in the Laney had partially shorted on one side of the centre tapped HT. Very happy with the result.
