Introduction
The original pins, used by Lundahl can sometimes break off, by soldering too fat wires on it. With this PCB, such damage can not happen, but most of all, this board makes sure you have always correct wiring and a professional appearance.
Features
- GOLD PLATED
- Works on all PP, SE, and PPZ transformers. (PPZ=Parafeed)
- PP offers a 50% Ultra Linear tap.
Connections
- LL1620/1627 and LL1623/9202 are connected different. For this, apply the solder bridge, at the right side, to use LL1623/LL9202 or at the left side, to use LL1620/LL1627.
- Single Ended (SE) , or Push Pull (PP) or Parafeed (PPZ) is automatically configured when the wires are soldered in at the right places.
- Ultra Linear Tap. Though this was not intended originally by Lundahl, the boards provide a 50% UL tap.
