[Heathkit] Dumb speaker question

[rbethman]

I just looked at my big TX-1 (1960) and my big HW-101 schematics.

They have VERY few voltage points, and quite frankly, they are small 
enough that even with my bifocals, the points are hard to read, and VERY 
sparse!

While I would in principal, agree to this philosophy, it would better be 
done on a Hallicrafters or Hammarlund.

Since we ARE talking Heathkit, we have a horse of a different color!
