LL1635: Lundahl Interstage Transformer

LL1635 is an interstage transformer for tube (valve) amplifiers available in Push-pull or Single-end versions. The transformer is highly sectioned and wound with a special low-capacitance winding technique, which results in excellent frequency response. The transformer has a unique high flux, low distortion audio C-core of Lundahl's production. NOTE: LL1635 is not suitable for SE to PP interstage. For this application, we suggest transformer LL1660 or LL1660S

The LL1635 is available in 3 options to suit the circuit topology. (The air gap is adjusted during manufacture to suit)

• Push-Pull
• 6mA Single-ended
• 20mA Single-ended

(N.B. The purpose of the airgap is to accept the DC current of the output valve without saturating the core, leaving enough headroom for the sound signal)

Turns ratio

• 1 + 1 : 1 + 1

Overall size including pins - 70mm x 61mm x 39mm
