[Vintage-Audio] Selecting Tape On H. Scott Amp

[WBob]

I do not have the specs or schematics on Duane's receiver. But the eq 
for tape heads and phono pickups is always done in the preamp. The 
mention of NAB, which is the tape EQ curve (RIAA is the Phono) and a 
switch that selects between the two quite different eq curves is a 
clear and undisputable indication that the preamp in Duane's receiver 
was intended to be used directly with tape heads and this was commonly 
done in the 60-70s. The line level tape loop input/output is flat and 
free from any eq. We are both right, in your saying the tape loop is 
flat and my saying that the phono input has switchable eq so it can be 
used for either tape heads or phono pickups. No flame intended, just 
an attempt to correct what I interpreted you to say in your original 
response...

Plus these thing should be discussed on the open mail as many folk are 
out there learning. They need and enjoy technical discussions.
