This is an alternate LND150 preamp output buffer that matches better with certain preamp PCBs that do not have a cathode follower.
- Goliath II (coming soon)
It will of course work well with Merlins Ultra High Gain Preamp also.
This circuit is powered from the B+ supply and needs 250-400v for optimal operation.
Please note this PCB is not for inexperienced users. You are working with high voltages that are potentially fatal.
