Line Output Transformer for Tube Amplifiers
LL1630
LL1630 is a line output transformer for tube amplifiers.
The transformer is highly sectioned, and wound with a special low capacitance winding technique. This results in
very good high frequency performance. The transformer has a special audio C-core of our own production.
