[Amps] Do you think he'll get it?

[Paul Christensen]

Roger,

I've long thought that ETO's product evolution was a bit interesting.  In 
the beginning, ETO produced the 70A, 70V, 77, 77D, 77Dx/Sx, all of which 
have remarkable circuit and cabinet similarities.  Perhaps these early amps 
sold in low volume which, may have then sparked the more economical designs 
of the 76, 374, and 78.  Clearly, these amps were built with the 
value-oriented amateur in mind with cost savings in areas like:

- Less expensive E core transformers with lower KVA ratings;
- Less expensive metal work, although the chassis work is still in a class 
far above that of Ameritron, Heath and Dentron;
- Lack of QSK;
- Honeywell/Schadow switches in place of Switchcraft crossbar types;
- Seemingly lesser-rated ceramic band switching;
- Multiple, lower plate dissipation tubes.

Today, I would likely steer away from the 76/374/78, especially at high 
prices.  The Alpha 86 can generally be obtained in the low $2K range.  I 
purchased one in new condition for that amount a couple years ago and it's 
significantly more robust than the 76, 374, and 78.

It's shame Dick Ehrhorn is no longer active on this list.  It would be 
interesting to hear his perspective on ETO's marketing thoughts going back 
to the early '70s.

Paul, W9AC
