Description

This assembled preamplifier board featuring the Nelson Pass B1 with Korg Nutube Triode is a high-quality addition to any home audio system. This assembled board is a Nelson Pass B1 with Korg Nutube triode. It’s a preamplifier. You could install it in a new chassis, or (perhaps) retrofit an existing component by subbing in this B1 for the preamp section. What’s next is up to you, some DIY required. This board is the OG—it’s the Christmas board. It predates the offerings sold as kits. It's been fitted with high end parts (Vishay Dale resistors and Nichicon audio capacitors) and spec'd out to handle up to 35V. Great condition.
