This amplifier , beautifully built by Cape Town EE John Gilmore is based
on the famous Dynaco ST70 . John designed the top plate as per the
Dynaco ST70 layout . Output transformers are the Dynaco A-470 (as in
ST70). Tests performed at Emil yesterday , these offer incredible
performance , -1dB @ 20hz to 0dB @ 30khz frequency response . Power
transformers are upgraded double stack made for ST70 , offering much
more power than the original . The amp tests for an incredibly low (for
valve amplifiers) 0.4% at full power output . Distortion will then be
much lower at reasonable listening levels . THD vs frequency tests
virtually flat from 20hz to 30khz .
SDS labs psu board under the hood is a huge improvement on standard ST70
PSU setup , offering better smoothing and more capacitance .
