McIntosh 275 OPT-a curious sidebar
In the mid-50's a college undergrad built a McIntosh style amp,
winding and documenting his OPT, and predating the trifilar primary in the 275 and the use of a winding for screen supply at lower voltage in the MI3500, by many years. However his distortion figures weren't that great. Poor choice of core material? |
