Easy answer â
Your sample Lankford-Misek-Ratzlaff phaser
Does not have actual matched 50 ohm potentiometers in the âfineâ controls â
They are âfakedâ 50âs using fixed resistors across the POT - which results in squirrelly, unpredictable or unstable nulls.
All M-L-R PHASERS âsoldâ since that beta was built have ceramic or wire wound pots built and deployed like Lankford made his.
Dallas Lankford described his 2007 Phaser as the best one ever - which is why Nick, Steve and I improved on it - making it significantly superior to the clunky Quantum Phaser and massively less expensive than the Cadillac-Tank DX-engineering Phaser.
And with this e-mail, Iâll expect pedantic pencil pointing, finger waving and demands to see schematics and exact details on all changes.
Iâm currently building 6 more simultaneously.
Iâm specifically not selling them to âgotta have one / gotta shelve one...â they are for active DXERS actually posting regularly on IRCA or one of the other clubs.
Iâll take questions now.
