I tested the taps and they seem ok Any ideas on using it in an application? There may be an input transformer available as well Attachments IMG_5105.jpeg 1.8 MB · Views: 0

S skeptic12 Well-known member GDIY Supporter Joined May 28, 2012 Messages 130 May 24, 2024 #3 Interesting! Why the 600ohm tap? I thought 2a3 had lower plate resistance and expected lower impedance on primary 7k in range for 6v6?
