Lundahl LL1620 Housing – ventilated steel cover for large audio transformers
The Lundahl LL1620 Housing is a four-part ventilated steel cover for large Lundahl audio transformers. It provides mechanical protection for terminals and windings and supports an enclosed above-chassis installation.
The cover is made from 2 mm construction steel and has a medium-dark charcoal semi-gloss powder-coated finish. Four mounting holes and a central cable opening support clean chassis installation.
Suitable applications
- Mechanical cover for large Lundahl output transformers
- Touch protection around open terminals and high-voltage wiring
- Visually consistent mounting on valve-amplifier chassis
- DIY and small-production amplifiers using the compatible hole pattern
- Retrofitting a closed cover where the chassis has adequate strength
Compatible Lundahl models
Lundahl lists the cover for models including LL1620, LL1623, LL1627, LL1648, LL1649, LL1650, LL1651, LL1679, LL2410, LL2414, LL2418, LL2419 and LL9202. Compare the transformer dimensions, terminal position and chassis cut-out with the current drawing before installation.

Installation notes
The amplifier chassis must safely support the installed transformer, typically weighing up to approximately 2.5 kg, together with additional mechanical loads. A thin chassis can require a reinforcing plate or larger washers.
Fit the cable opening with a suitable insulated bush, grommet or strain relief. High-voltage wiring must not rub against sharp steel edges and requires adequate clearance from the cover and mounting screws.
Do not obstruct the ventilation openings. The cover does not replace electrical insulation of the terminals or a correctly designed protective-earth and chassis system.
