Description

Turns Ratio: 4 x 13:4 : 8 x 1
The LL1620, LL1623, LL1627 and LL9202 are output transformers for tube amplifiers. All transformers are based on the same core size, winding structure and secondaries, but differ in n umber of turns (and thus impedance level) of primaries. The transformers are highly sectioned with harmonically sized sections, which results in a minimum leakage inductance. This, combined with a low capacitance coil winding technique results in a wide f requency range. The transformers have a special audio C - core of our own production, which is gapped for desired DC current. The transformers are of open frame type suitable for mounting inside an amplifier housing.

    Perfect product and first class service. Verry good packing and fast shipping. The Lundahls are first class and way better than the Edcor output transformers that I have using till now in my 300b tube amps. Thank Don audio!
